摘要
通过对较大尺寸的裂隙岩体试块进行不同侧压力和加载条件下的渗流试验结果研究，分析了裂隙岩体渗流与应力的耦合机理，得出了不同应力条件下裂隙岩体渗流量与应力成四次方的关系。并且得出并非压应力都引起裂隙岩体的渗流量减小，当裂隙岩体受平行于裂隙面方向的单向压应力时，渗流量随着压应力的增加而增加。
Through experimental study of large rock sample containing a group of fractures under different confined stresses, the coupled seepage flow-stress mechanism is discussed. The test results illustrate that there is a relationship of one-fourth power between the seepage-flow and the stress. The compressive stress does not necessarily cause the decrease of the seepage flow. When fractured rock is subjected to the compressive stress parallel to the main fracture plane, the seepage flow increases with the increase of the compressive stress.
