Description
Technical field
The utility model relates to a kind of on-the-spot permeability experimental facility of discrete material, belongs to Geotechnical Engineering field, mine.
Background technology
Soil has the performance being seen through by water and is called native perviousness.Penetration property is the important engineering properties of the soil body, the intensity property of the decision soil body and distortion, fixed character, and infiltration problem is one of three major issues of soil mechanics, with main three large problems of strength problem, the synthetic soil mechanics of problem on deformation.Simultaneously, coefficient of permeability K is an index of concentrated expression soil body penetration ability, also a basic parameter must using while being seepage calculation, the correct of its numerical value determines for the seepage stability calculating of analyzing the dam body dam foundation, excavation of foundation pit side slope and other nature and Artificial Side-slope have very important meaning.Different types of soil, K value difference is very not large.Therefore, measuring accurately native infiltration coefficient is a very important job, and the correct of its numerical value determines that infiltration calculation is also had to very important meaning.The factor that affects infiltration coefficient size is a lot, as glutinousness of the shape of soil body particle, size, nonuniformity coefficient and water etc., set up the accurate Theory formula comparison difficulty of calculation permeability coefficient K, conventionally can carry out true defining K value by test method (comprising experimental determination method and on-site measurement method) or empirical estimation method.
Current experimental determination method has " constant head test method " and " varying head test method(s) " two kinds, but the distinct disadvantage due to experimental determination method self: soil sample level of disruption is large, the original composition structural failure of the soil body is serious, and the actual value of its experimental result and the on-the-spot soil body has larger difference.Compared with experimental determination method, the advantage of on-site measurement method maximum is just that it can farthest retain the original composition structure of the on-the-spot soil body, and less to the disturbance of the soil body, and accurately simulated field condition, so can obtain more exactly the infiltration coefficient of the soil body.However, that current field testing procedure (comprising the method for testing pits, monocycle method and dicyclo method etc.) has is consuming time, effort, cost are high, be subject to seasonal effect, only in the evaluation at some heavy constructions or water source, adopts at present.Common engineering limited investment, the duration is short, and the mensuration of infiltration coefficient is difficult to adopt existing field testing procedure.Meanwhile, because natural Rock And Soil has nonuniformity and anisotropy in varying degrees.And percolating medium is assumed to homogeneous and isotropy by the assay method of most, the infiltration coefficient obtaining is an integrated value.In fact, homogeneous soil is also not necessarily isotropic.Natural Rock And Soil all has nonuniformity and anisotropy in varying degrees.The reason that non-homogeneous water permeability forms be mainly due to the existence of bedding with and the difference of trend, particle composition and structural difference thereof, the growth unevenness in hole and crack etc.For on-the-spot discrete material, there is to a certain extent heterogeneous anisotropic, therefore infiltration coefficient respectively level to vertical on definite be essential.
Therefore, in order to overcome the shortcoming of experimental determination method to " soil body composition structural perturbation degree is large ", simultaneously for the shortcoming of field testing procedure " consuming time, effort, cost high, be subject to seasonal effect ", the utility model has been developed a kind of on-the-spot permeability experimental facility of discrete material, this installs compared with prior art, has the following advantages and effect: the permeability test of carrying out at the scene discrete material in the situation of undisturbed sample structure (the group structure of soil); Simultaneously, in order to consider nonuniformity and the anisotropy of the natural soil body, this on-the-spot permeability experimental facility can not only be measured respectively to same soil sample " vertical infiltration coefficient " and " horizontal permeation coefficient ", and can also measure respectively " the horizontal permeation coefficient " of the same soil body at two different directions; Thereby raising experimental precision.In addition, with existing on-the-spot permeability test method, not only save a large amount of human and material resources and financial resources, also greatly improved the accuracy of the coefficient of permeability K of surveying.
