摘要

基于三维有限元法，对刘家峡水电站扩机工程调压井结构进行了静力、反应谱分析及非线性有限元分析，评价了结构的荷载效应。首先根据线弹性有限元分析结果，采用拉应力图法对调压井衬砌结构进行了配筋；然后以考虑混凝土开裂的非线性有限元方法校核结构强度和裂缝宽度。通过调整配筋面积，提出了适合于该水电站扩机工程调压井结构的最优结构型式和配筋方案。

Abstract

Based on three-dimensional finite element method

the static analysis

spectrum analysis and nonlinear analysis of the structure of surge chamber of Liujiaxia Hydropower Station have been carried out. Load effects are evaluated in this paper. In accordance with the results of linear FEM analysis

a design scheme of reinforcement is proposed. Then

the strength of the structure and crack width are checked by using the nonlinear FEM. After several times of adjusting steel bars area of the structure

an optimal structure and corresponding reinforcement are obtained.
