摘要
从岩土力学的角度对水库蓄水后坝基和坝体形成渗漏裂缝的机理进行了理论计算和对比,结果表明,大高度蓄水静水压产生的附加应力并不是形成渗漏裂缝的主要因素,而一定高度蓄水引起岩土体内孔隙压升高到极限值才是产生破坏性裂缝、形成渗漏的主要原因.
Mechanism of leaky fracture formation in water storaged dam foundation and dam body has been calculated theoretically and compared from the point of view of rock and soil mechanics.The result indicates that the main reason for the leaky fracture formation is not the stress caused by the hydrostatic pressure of greatly high storaged water,but the going up of pore pressure to a limit value in rock and soil body under certainly high storaged water.
