Background
The stability of the dam slope of the earth-rock dam is an important work in the engineering design process, and the traditional dam slope stability analysis adopts a single safety factor method, namely a safety factor F expressed by the ratio of resistance and action effect. In this definition method, both the resistance and the acting force are represented by a constant value, and uncertainty factors such as a calculation model and calculation parameters cannot be considered. The traditional single safety coefficient method can not fully reflect the design difference and sensitivity, and the allowable value of the safety coefficient is also determined by engineering experience, so that the traditional safety coefficient can not fully reflect the design difference and sensitivity. The reliability analysis method can provide a systematic and quantitative solution for uncertainty factors contained in geotechnical engineering. In order to consider the uncertainty of material parameters when analyzing dam slope stability, it is necessary to recheck and calculate the stability by a reliability method on the basis of the traditional safety coefficient method.
In general, the shear strength index of the soil is generally calculated by using a linear molar coulomb formula, wherein the calculation formula is as follows:
where τ is the shear strength of the earth, c is the effective stress shear strength cohesion, σ n Is the normal effective stress of the device,is the effective stress shear strength friction angle.
The existing specification (grinding type earth-rock dam design specification) NB/T10872-2021 specifies that coarse particle materials such as rock-fill, broken stone, sand gravel and the like are calculated by adopting nonlinear shear strength indexes, and the calculation formula is as follows:
wherein sigma 3 Is a small principal stress, which is a small principal stress,is an internal friction angle at atmospheric pressure, < >>Is sigma (sigma) 3 Increase the internal friction angle under one logarithmic period +.>Reduced value of p a Is at atmospheric pressure.
When the stable and reliable index of the dam slope is calculated, if the nonlinear intensity index shown in the formula (2) is adopted, the calculation of the reliable index of the earth-rock dam is complicated.

As shown in FIG. 1, the method for analyzing the stability of the dam slope of the earth-rock dam provided by the invention comprises the following steps:

Step 103: and analyzing the stability of the dam slope of the earth-rock dam based on the reliability index.
In the practical application process, the Taylor series expansion of the formula (2) is mainly used for deducing and establishing the conversion relation between the nonlinear strength parameter and the linear strength calculation parameter of the earth-rock dam, namely, the relation between the formula (2) and the formula (1) is established, and based on the relation, the concrete implementation process of the earth-rock dam slope stability analysis method provided by the invention can be as follows:
the unified standard of the reliability design of the Chinese engineering structure (GB 50153-2008) requires that the action effect S and the resistance R of a building are compared, and the corresponding limit state function G is as follows:
G＝R(·)-S(·)＝0 (3)
wherein R (&) and S (&) are random variable functions of the action effect.
Under the assumption that the limit state function G obeys normal distribution, a reliable index is defined as β:
wherein mu G Sum sigma G The mean value and standard deviation of the limit state function G, respectively.
In the reliability analysis of the earth-rock dam of the present invention, only the cohesion c and the internal friction angle of the earth are consideredBased on this, equation (2) can be expressed as:
G＝R(c 1 ,f 1 ,c 2 ,f 2 ,..,c n ,f n )-S＝0 (5)
wherein the cohesion c and the internal friction coefficient f are random variables for calculating the resistance function R (& gt), and the internal friction coefficient f is the internal friction angleTangent of (i.e.)>n is the number of different soil layers.
For the stability of the dam slope of the earth-rock dam, the safety coefficient F is defined as:
the limit state function G is:
G＝F-1＝0 (7)
according to the formula (4), the reliable index beta of the dam slope of the earth-rock dam can be defined as follows:
wherein mu F Sum sigma F Is the mean value and standard deviation of the safety coefficient.
The calculation process of the anti-slip stability of the arc sliding strip method is shown in figure 2 according to the rolling earth and rockfill dam design Specification NB/T10872-2021. The safety factor F is calculated by adopting a simplified Chinese zodiac method which takes the action force between the bars into account, and is as follows:
wherein F is a safety coefficient, W is the gravity of the soil strip, V is the vertical inertial force, u is the pore pressure acting on the bottom surface of the soil strip, alpha is the included angle between the gravity line of the strip block and the radius passing through the midpoint of the bottom surface of the strip, b is the width of the soil strip, c 'is the standard value of the adhesive force of the effective stress shear strength of the bottom surface of the soil strip, phi' is the standard value of the friction angle of the effective stress shear strength of the bottom surface of the soil strip, M c The moment of the horizontal inertia force of the earthquake to the circle center is represented by R, and R is the radius of an arc. In fig. 2, Q is the seismic horizontal force.
In the formula (9), the material strength parameter test is adopted to obtain the parameter cohesion c and the internal friction angleThe mean value calculation of (1) is the safety coefficient mean mu F 。
Standard deviation sigma of safety factor F The simple analytical method using j.m. duncan was calculated as follows:
1) By using test systemsMetering method, estimating cohesion c and internal friction angle by empirical mean and coefficient of variation or "3 sigma criterion" methodStandard deviation of (2).
2) Under the condition that other parameters are kept unchanged as most possible values, the safety factor F+ value and the safety factor F-value are calculated by adding one standard deviation to the average value of each parameter and subtracting one standard deviation, namely F+ represents the average value of each parameter plus one standard deviation, and F-represents the average value of each parameter minus one standard deviation. If there are m parameters in total, 2m calculations are performed, which will result in m values of the safety factor f+ and m values of the safety factor F-. The mean variable, Δf, is calculated from the safety factor f+ and F-values of each parameter, based on which the standard deviation of the safety factor can be calculated as:
ΔF i i=1, 2,..n, is the average variable of the safety coefficient of the ith soil layer.
In soil mechanics, cohesion c and internal friction angleThe shear strength index tau of the soil is used for representing. The shear strength index tau of the soil is usually calculated by adopting a linear molar coulomb formula, and the concrete expression is shown in a formula (1).
For non-clay soil, its cohesion c is 0. Equation (1) can be simplified as:
the existing specification (grinding type earth-rock dam design specification) NB/T10872-2021 specifies that coarse particle materials such as rock-fill, broken stone, sand gravel and the like are calculated by adopting nonlinear shear strength indexes, and the calculation formula is as follows:
wherein sigma 3 Is the effective small principal stress of the soil body,is a friction angle at atmospheric pressure, < >>Is of small principal stress sigma 3 Increase the internal friction angle under one logarithmic period +.>Is a reduced value of (2).
To reduce the problem of difficult convergence caused by non-linear parameters, equation (12) is converted into equivalent linear intensity parameters.
Bringing formula (12) into formula (11), yields:
formula (13) is shown in sigma n,o The Taylor series expansion is adopted at the position, and the method is obtained:
let DeltaSigma n ＝(σ n -σ n,0 ) Obtaining:
let sigma n =0, yielding:
wherein c is the equivalent cohesion of the coarse particles.
Bringing formula (16) into formula (15), yields:
comparing formula (7) with formula (17), it is possible to obtain:
in the method, in the process of the invention,is the equivalent internal friction angle of the coarse particles.
And sigma (sigma) n Sum sigma 3 The relationship of (2) can be expressed as:
therefore, there are:
the equivalent linear strength τ of the final coarse particles is:
equivalent internal friction angle of coarse particlesAnd substituting equivalent linear intensity tau into the formulas (5) to (10), and calculating a reliable index, thereby realizing the purpose of evaluating the stability analysis of the dam slope of the earth-rock dam by adopting nonlinear intensity parameters.
