采用非线性有限元与解析法相结合,对积石峡水电站压力钢衬钢筋混凝土压力管道进行了钢衬厚度和钢筋配置设计,并分析了产生裂缝的地方。计算结果表明结构设计合理、安全,满足工程要求,为类似工程可提供设计借鉴。
Based on the combination of nonlinear finite element method and analytical method, the design of steel lining thickness and reinforcement configuration for pressure-lined steel-reinforced concrete pressure pipe at Jishixia hydropower station was carried out and the place where cracks were generated was analyzed. The calculation results show that the design of the structure is reasonable and safe and can meet the engineering requirements and provide reference for similar projects.
