Comparative Analysis of Thickening Schemes of An Arch Dam Based on Finite Element Internal Force Method
摘要
Abstract
With the increase of service petiod,gradually aging and various sick of arch dam appeared. Thichen-ing of arch dam has been a widely adopted measure and its technique and safety is receiving more and more attention. The finite element internal force method is used to calculate and analyse the dam stresses and its two design schemes, i. e. to thichen at the downstream surface and at the upsteam face. Through comparing the dam stress state between the two schemes, it is shown that the scheme of thichening at the downstream surface is more fitting to engineering application. This can provide the foundation for choosing a reasonable scheme for the dam thichening. The results show that the finite element internal force method is correct through checking with the results of the equivalent stress method and the the multi-cantilever method.关键词
