Abstract: Using finite element analysis method and selecting representative profile of the dam in Xiaowan River,model and mesh were set by ANSYS software.Simulation engineering stage and grading load location,two dimension finite element stress and strain were calculated in completion period and storage period.The maximum vertical displacement and horizontal displacement of the dam upstream and downstream,big and small principal stress of the dam,along the slope stress of the face plate and surrounding seam shear or stretching displacement in different periods had been analyzed.The results showed that the change of the horizontal displacement was smaller than that of the vertical displacement.The stress level of dam was not high.The stretch displacement and shear displacement of surrounding seam were small.The face plate deformation was coordination,and stress strain of the dam could meet safety requirements.According to engineering example,this calculation method was simple and intuitive,which could meet the accuracy requirement.
