使用劈裂方法在粗砂岩岩样上制造裂隙来模拟粗砂岩天然岩体的张性裂隙,在电液伺服岩石三轴试验机上开展单裂隙渗流应力耦合试验.在三维应力下,检测在不同嗣压、水压情况下,渗流量随时间的变化情况,对单裂隙岩体在三维应力作用下的渗流规律作了探究.%A single fracture in sandstone rock was formed by splitting to simulate the natural extension fracture.Coupling experiments on stress and seepage of the rock with single fracture were performed through electric-fluid serving triaxial compression machine.Examing how seepage flow changes with time by different confining pressures and water pressures under triaxial stresses.And making a discussion on the seepage laws in sandstone within single fracture under triaxiality stresses.
