摘要
基于某大型引水隧洞地应力实测结果,提出了侧压力系数的有限元数值反演方法,并开展工程区域地应力场的反演计算,反演结果与实测结果较为吻合,从而得到了工程区域地应力分布规律,为引水隧洞工程的设计、施工与支护提供了参考。
A 3DFEM model was established on the MATLAB platform to backcalculate lateral pressure coefficient for a large size diversion tunnel from insitu stress measurement.The backcalculated results indicate the FEM inversion method proposed is feasible and provides a reference for the design,construction of the supporting system of the diversion tunnel.
