摘　　要：水电站进水口渐变段钢衬结构在外水压力作用下,往往会发生大的变形屈曲破坏。为此,对某水电站进水口渐变段钢衬结构,进行了在外水压力作用下结构刚度及强度的分析,提出了渐变段钢衬结构分析的刚度及强度设计准则。同时指出,渐变段钢衬结构分析问题不属于结构稳定性问题,而属于结构刚度和强度问题。Under the external water pressure, the steel linings of the intake transition sections are often subject to great deformation and yielding failure, therefore, studies are made on the structural rigidity and strength of the steel linings under external water load of the intake transition sections at a hydroelectric project and based on the results of these studies, the design criteria for rigidity and strength of steel linings of the intake transition sections are presented. The paper also indicates that the structural analysis of the steel lining for intake transition section is not a structural stability analysis, but a rigidity and strength analysis.
