四川地区某水电站引水发电洞压力隧洞结构受力情况复杂,隧洞衬砌结构配筋计算是工程的重要环节。运用三维有限元仿真技术进行模拟计算分析,选定衬砌结构配筋的参数。实践证明三维有限元仿真计算方法可靠工程运行多年,隧洞衬砌监测数据正常。
The stress of tunnel structure in diversion and power generation in a hydropower station in Sichuan Province is complex and the reinforcement calculation of tunnel lining structure is an important part of the project. Using three-dimensional finite element simulation technology to simulate and calculate and select the parameters of lining reinforcement. Practice has proved that three-dimensional finite element simulation method for reliable operation of the project for many years, the tunnel lining monitoring data is normal.
