摘要
以摩洛哥某水电站具有复杂围岩条件的有压引水隧洞为例,选取围岩条件最差的隧洞断面,运用非线性有限元法,对隧洞开挖、衬砌及运行过程中的应力变形进行了有限元仿真分析,探讨了复杂围岩条件下有压隧洞施工期及运行期应力变形的分布与变化规律。
Taking a pressure tunnel with complex geological condition in Morocco as an exampleand selecting the worst condition section, the non-linear finite element method is used to simulatebased analysis for the stress distribution and deformation in tunnel construction and operation periods, discussed the stress distribution and deformation rules of the pressure tunnel construction and operation period under complex geological condition.
