To monitor the stability of the retaining dam of Linxi reservoir,the finite element method is used to calculate and simulate the mechanical properties of the dam.At the same time,the stability of the dam slope was calculated using the strength reduction method.The results show that the finite element analysis of seepage flow at the upper water level of 72.19m is 69.1m3/d.When the reservoir is at the dead water level,the dam body is reduced to 0.896,and there is basically no seepage damage.The safety factors of anti-sliding stability of dam slope under the three working conditions are 1.43,1.29 and 1.21 respectively,which do not exceed the limit value.The research provides a very important reference value for dam reinforcement and management.
