A typical section(K0+515m) of left spillway tunnel of JinPing hydro-power station is modeled in detail considering joint distribution using non-linear finite element method.
本文采用非线性弹塑性有限元法,对锦屏电站左岸导流洞塌方洞段的典型剖面K0+515m进行了精细模拟,研究了开挖过程中不支护与支护后洞周围岩应力应变分布及变化规律、洞周边变形及洞周塑性破坏区范围的变化,分析了局部洞段围岩失稳的成因,结果表明高地应力、洞周层面和裂隙及其特定组合是导致洞周局部不稳定的主要原因, 并预测了洞周可能存在的不稳定部位,进而对拟定的加强支护措施的有效性作出了评价,为支护的优化设计提供依据。
