泥浆在土层中渗透的测试装置及测试方法
摘要：
本发明涉及一种泥浆在土层中渗透的测试装置，包括：土样夹持器，内夹持有依照地层土样所处的地层压力进行重塑的地层土样；与所述土样夹持器连接的第一高压气源，用于对所述土样夹持器施加围压；设于所述土样夹持器内的泥浆管，所述泥浆管内注有泥浆，且所述泥浆管的顶端为密封结构，底端为开口结构并与所述地层土样的上表面相接触；与所述泥浆管顶端连接的第二高压气源，用于对所述泥浆管施加轴压；以及连接于所述土样夹持器上与所述地层土样下表面对应的一端的导出管，用于导出从所述地层土样渗透出的泥浆滤液。克服了现有技术中未考虑土样所受的压力的问题，本发明所测得的结果更加准确可靠。
摘要（英）：

The invention relates to a testing device for permeation of slurry in a soil layer.The device comprises a soil sample holder, a first high-pressure air source, a slurry pipe, a second high-pressure air source and a leading-out pipe.A soil layer sample remodeled according to the pressure of a stratum where the stratum sample is located is clamped in the soil sample holder.The first high-pressure air source is connected with the soil sample holder and used for applying surrounding pressure to the soil sample holder.The slurry pipe is arranged in the soil sample holder and filled with slurry, the top end of the slurry pipe is of a sealed structure, the bottom end of the slurry pipe is of an open structure, and the bottom end of the slurry pipe is in contact with the upper surface of the stratum soil sample.The second high-pressure air source is connected with the top end of the slurry pipe and used for applying axial pressure to the slurry pipe.The leading-out pipe is connected to the end, corresponding to the lower surface of the stratum soil sample, of the soil sample holder and used for leading out slurry filter liquid permeating out of the stratum soil sample.The problem that the pressure borne by a sample is not considered in the prior art is solved, and a result measured through the testing device is more accurate and more reliable.
