摘要
介绍一种自主研发的破碎岩石三轴渗流试验装置,结合DDL600电子万能试验机改变其轴向位移或压力,围压泵用于给破碎岩石加载环向载荷,渗透压泵可以调节试样两端渗透压大小。3套独立系统的结合使用可测试在三维应力下破碎岩石的渗透特性参数,并用该系统对破碎砂岩进行了渗透试验,验证了其可行性。
Introduces a self-developed three axis rock seepage permeability test device, with the DDL600 electronic universal testing machine changing its axial displacement or pressure, with the confining pressure pump loading circumferential load for broken rock, and with the osmotic pump adjusting the pore pressure at the two ends of the sample. The permeability parameters of the broken rock under three-dimensional stress of rock can be tested by combining these three sets of independent systems together. The systems can also be applied to test the permeability of broken sandstone and to verify its feasibility.
