Abstract
The treatment effect of dam foundation fracture zone is related to dam safety, A case is provided base on the fault-fracture zone with large permeability in a core dam foundation in Xinjiang province, The dam foundation seepage model is established with the seepage finite element method base on The test results of post-grouting in the fault-fracture zone, simulation working conditions of different curtain depth and permeability indicate that significant impervious effects of compound grouting and depth-curtain at fault zone, leakage is less in the dam foundation and seepage stability meet the requirement on the riverbed overburden in the downstream, The results are high reference value for similar projects.
