Three-Dimensional Finite Element Numerical Simulation Analysis of Overflow Crest Outlet of Arch Dam in Severe Cold Area
As an important sluice structure of arch dam,the overflow crest outlet plays an important role in the safe operation of the dam.Taking the overflow crest outlet of an arch dam as an example,the crest outlet is located in the high latitude cold area,the structure is complex and the seismic intensity is high.The static and dynamic stresses of the crest outlet under different working conditions are calculated and analyzed by the three-dimensional finite element method.According to the calculation results,the reinforcement design of the crest outlet structure is carried out to determine the arrangement and reinforcement amount of the tensile reinforcement,so that the reinforcement arrangement of the crest outlet structure can meet the bearing capacity and normal use requirements.The research results can provide reference for the reinforcement design of similar projects.
