本文采用非线性有限元方法分析了普通钢筋砼衬砌压力引水隧洞在地应力场和内水压力作用下围岩和衬砌共同工作的受力特点。计算结果与仿真材料模型试验结果在规律上是基本一致的。
In this paper, the non-linear finite element method is used to analyze the force characteristics of common reinforced concrete lining pressure diversion tunnel under the action of in-situ stress and internal water pressure. The calculated results are basically the same as those of the simulated material model test.
