| Abstract: | There was a large developed scale of crush-caused fractured zone in the gravity dam foundation of hydropower station engineering. The actual hydraulic condition was simulated to study the failure model and level of rock mass with crush-caused fractured zone by the in situ high pressure seepage deformation test, in which the seepage gradient, including the critical gradient and the failure gradient, and the failure model were obtained. |
