【摘要】 基于裂隙充填物膨胀压力与蚀变岩体力学参数测试分析成果,针对膨胀性充填物对裂隙岩体渗流影响极少开展的问题,探讨了充填物的力学响应对裂隙渗流的影响。研究表明,无论充填物产生的膨胀压力对裂隙来说是剪应力还是拉应力,都将导致其渗透性显著增加。并且,充填物的塑化、液化效应也对裂隙渗流产生重要影响。更多还原

【Abstract】 Based on the testing results for the mechanical parameters of altered rock mass and on the comparison of the expansion stress of fracture fillings,the mechanical effects of the fillings on fracture seepage are discussed.The study shows that the permeability of the fillings will greatly increase whether the expansion stress from the fillings is shear stress or tensional stress,and the effects of the plasticization and liquefaction of the fillings will influence the fracture seepage.更多还原
