| 摘 要： | 在综合分析坝内埋管现行设计理论和方法的基础上，提出了坝内埋管极限状态设计方法. 该方法以钢筋混凝土非线性分析为主要手段，可以同时考虑坝体荷载、内水压力、温度荷载的作用，全面分析坝内埋管中钢管、钢筋和混凝土的应力状态和承载情况，并决定钢管壁厚和外围坝体混凝土的配筋，它对于改进坝内埋管的强度设计，具有重要实际意义。

| Abstract: | Based on the comprehensive analysis of the current design theory and method for penstock embedded in dam, a design method of limit state has been brought forward in this paper. By means of the nonlinear finite element analysis of reinforced concrete, this method can be used to analyze the stress state and bearing capacity of the penstock embedded in dam under body load, internal water pressure and temperature load. The thickness of the penstock and reinforcement in concrete of the dam body can be determined. It has practical significance in improving the strength design of the penstock embedded in dam. |
