摘　　要：由于水电站厂房的结构形式复杂,结构的受力和边界条件等也比较复杂,常规的结构分析方法难于准确了解结构的变形规律和应力分布。考虑实际情况,并进行适当简化,取边机组段厂房与安装间的有限元模型做整体结构分析。计算以弹性结构力学和结构动力学理论为基础,采用通用ANSYS程序,当地基静动态强度和刚度不足时,提出符合工程实际的基础加固处理方案建议。Due to the complex structure form of hydropower plant,the stress and boundary conditions of the structure are also complicated,so it is difficult to accurately understand the deformation law and stress distribution of the structure by conventional structural analysis methods.Considering the actual situation,this paper takes the finite element model of powerhouse and installation room of side unit section for overall structure analysis.This calculation is based on the theory of elastic structure mechanics and structural dynamics,and the general ANSYS program is adopted.When the static and dynamic strength and rigidity of foundation are insufficient,suggestions for foundation reinforcement treatment scheme which conforms to the actual engineering are put forward.
