| 摘 要： | 根据罚函数思想，应用虚功原理，建立了协调元法有限元方程。将协调元法与非线性分析相结合，对一实际工程中的钢衬钢筋混凝土联合承载组合结构进行了分析，研究了不同力学模型和不同内压形式对结构内力的不利影响。研究表明，非均匀内压和钢衬的抗剪与抗弯刚度对结构中内力分布影响较大；在钢衬钢筋混凝土管道结构设计中应充分考虑其影响，以策安全。

| Abstract: | A simple and effective penalty element method is presented which can be used to study a large compeite structure composed of different kinds of components. Combining penalty-element methed with nonlinear analysis,a practical compoite structure of the steel liner reinforced concrete penstock is analyzed and the unfavourable influence on the structure are studied under the different mechanical models of the steel liner and the different forms of the internal water pressure loading. |
