渗流压力对岩土强度及地应力对岩土渗透性影响实验装置
摘要：
本发明渗流压力对岩土强度及地应力对岩土渗透性影响实验装置，属于岩土力学测试技术领域；不同深度的地层中注浆，土体或岩体所受处的应力状态和渗透系数也不同，现有技术无法在渗透发生过程中测量岩土的强度，以及在受压状态下测量岩土的渗透系数；本发明提供一种渗流压力对岩土强度及地应力对岩土渗透性影响实验装置，试件放于试样存放装置中并用柔性材料包裹保护，水头差提供渗流压力，压力机测试岩土强度，利用压力机为试件提供压力模拟地应力，采用通过测不同渗流压力下单位时间内的流量计算渗透系数；本发明可广泛应用于岩土力学测试领域。
摘要（英）：

The invention discloses an experiment device of influences of seepage pressure on rock and soil strength and ground stress on rock and soil permeability, and belongs to the technical field of rock andsoil mechanics testing. Grouting in strata of different depth is carried out, stress status and permeability coefficients of soil or rock mass are also different, and the prior art cannot measure thestrength of rock and soil in an infiltration process and measure of a permeability coefficient of the rock and soil in a compression state. The invention provides the experiment device of the influences of the seepage pressure on the rock and soil strength and the ground stress on the rock and soil permeability. A test piece is placed in a test sample storage device and is wrapped and protected by using flexible material, water head difference provides the seepage pressure, a pressure machine tests the rock and soil strength, and is used to provide pressure for the test piece to simulate theground stress, and a manner of calculating the permeability coefficient through measuring flow rates in unit time under the different seepage pressure is used. The device can be widely used in the field of rock and soil mechanics testing.
