Seepage Stability of the Dam Foundation of Luhun Reservoir

摘要

Based on the supposed seepage model and the boundary conditions of the dam foundation, this paper, with numerical simulation and statistical method as research method, centers on the hydraulic gradient of the seepage field and the seepage stability of the dam foundation of Luhun Reservoir. According to the study, the dam functions well because when the reservoir is slowly filled with water, the hydraulic gradients of the cutoff trench, the belt of overflow, and the fault fracture zone of the dam foundation are much smaller than the allowable index, posing no danger to the stability of the dam foundation. This study furnishes theoretical support to the normal work of the reservoir when the supposed water level is 319.5m, 327.5m, 331.8m.
