Abstract
Aiming at the danger removal and reinforcement project of a large reservoir,this paper comprehensively considers the actual engineering conditions and corresponding geological conditions.Numerical models are established by using MIDAS GTS NX and Autobank software respectively,and finite element method is adopted to carry out analysis,so as to recheck the seepage stability and slope stability of the dam under both normal and abnormal operating conditions.The analysis results show that the distribution laws of phreatic line under various working conditions are reasonable.The seepage gradients at the dam toe exit are all lower than the allowable seepage gradients,the exit points are at relatively low positions,and the seepage discharge is quite small.Moreover,the calculated stability safety factors are all higher than the allowable values specified in relevant codes and specifications,indicating that the seepage stability and slope stability of the dam meet the standard requirements.The research results can provide reference for the danger removal and reinforcement design of similar earth-rock dams.关键词
