摘　　要：本文利用有限元理论，选取适用于混凝土材料的非线性本构关系．在蜗壳上部有关荷载、结构自重和内水压力联合作用情况下，对蜗壳钢衬、不同材料垫层和外包钢筋混凝土的联合作用结构进行计算分析．给出了结构控制部位各种材料的承载比与垫层弹模的关系．为工程建设提供了设计依据．In this paper, Non-Liner constitutive equation suited to concrete material is selected,According to the finite element theory. On the condition ofstructure weight and pressure of inner water, jointly loaded spiral case structure,which include steel lining, different material cushion layer and reinforcedconcrete structure around spital case. The relation of some different material bearing ratio in Important positions and elesticity modules of cushion are obtained.It provide deSign basis for the project.
