摘要
以阿海水电站为例,采用有限元理论,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下,计算分析了蜗壳钢衬、不同厚度垫层和外包钢筋混凝土的联合作用结构,给出了蜗壳应力及外围混凝土应力与垫层厚度的关系。
Taking Ahai Hydropower Station for an example,under the joint action of upper spiral case loading,structure weight and internal water pressure,joint structure are calculated and analyzed by choice of non-linear constitutive equation for concrete material with finite element theory,which includes steel lining,different thickness of cushion layer and reinforce concrete structure around spiral case.And then the relationship between stress（concrete stress spiral case stress） and thickness of cushion layer is obtained.
