3D Finite Element Analysis of Prestressed Pier Structure on Surface Spillway
摘要
Abstract
It is a key problem to understand the stress distribution and deformation performance of prestressed pier structure on surface spillway. To ensure safety of the whole structure in construction and operation, a-nalysis of prestressed pier structure on surface spillway of a hydropower station is carried out by using AN-SYS software. Then the distribution regularity of deformation and stress on the whole structure at typical operation condition was obtained. According to the results, concrete structure's prestressed effect is evaluated; and the two schemes of prestressed system of different pull-anchor coefficients were compared and discussed. The results provide a scientific basis for the design and optimization of pier structure.关键词
