Description
Technical field
The present invention relates to soil body index test field, more particularly, to a kind of bury soil in-situ test device and test side
Method.
Background technology
The conventional method of the test intensity of clay and index of correlation mainly has a unconfined compression test method, triaxial tests method,
Vane-shear method, but for dead-soft clay, moisture content is high because it has, and effective stress is low, the features such as intensity difference, so no
Method carries out intensity and deformation test with traditional strength test method.It is usually used at present measuring dead-soft clay undrained strength
Method has rotation viscometer method, flat board penetration method, miniature four-bladed vane method etc..
The yield strength of soil sample when using rotation viscometer to obtain different rates in rotation viscometer method, and by yield strength
With the Changing Pattern extension of shear rate, obtain the undrained strength that the yield strength that shear rate is when zero is soil sample.Aobvious
So, because rotation viscometer method is a kind of method of indirectly testing undrained strength, and obtain undrained strength data precision relatively
Difference, so when measuring undrained strength with epitaxy, the error being caused by human factor is larger, additionally, rotation viscometer
Test is the undrained strength that the undrained strength that dead-soft soil is reinvented during state completely cannot test weak soil after deposition.Flat board passes through
Enter method to be proposed by Inoue etc. earliest, the method is to carry the stiffener plate carving angle injection several times under Gravitative Loads by 1 piece to survey
The not draining that examination soil layer, the slope according to pile penetration and loading capacity linear relationship and native unit weight can calculate this soil layer of acquisition is strong
Degree.The undrained strength that flat board penetration method obtains is higher than that rotation viscometer method obtains, and the intensity of flat board penetration method test is flat
Undrained strength between plate and soil sample, this intensity is generally below the actual strength of soil layer；Additionally, the soil of flat board penetration method test
The unit weight of layer is identical along depth needs, just can ensure that pile penetration is linear with loading capacity, cannot be used in this way sinking
Weak soil undrained strength test after long-pending.The test philosophy of miniature four-bladed vane method is identical with traditional four-bladed vane method, due to miniature cross
High-precision force snesor is employed, so measuring accuracy is higher than traditional four-bladed vane method in panel assembly.
Because dead-soft clay has, moisture content is high, and effective stress is low, it is impossible to obtain original state examination from scene the features such as intensity difference
Sample, therefore tradition interior experimental technique (such as no confined compression experimental method, triaxial tests method) cannot be carried out intensity and deformation test.
Rotation viscometer method, flat board penetration method, miniature four-bladed vane method etc. can only test pole bury intensity it is impossible to test
Strain, thus E can not be obtained by test result50(strain modulus) index.
