摘要
采用三维快速拉格朗日差分法(FLAC3D),对琅琊山抽水莆能电站地下厂虏洞室开挖与支护过程进行了数值模拟。研究了地质条件具有代表性的1#机组及较为复杂的2#机组剖面,对开挖后围岩的应力场、位移场及塑性区特征进行了比较分析,得出了一些建设性的结论,对工程的施工具有指导意义。
Using Three-Dimensional Fast Lagrangian Analysis of Continua (FLAC3D) method, the excavation and the effect of support are simulated for underground power-house of langyashan pumped-storage power station. For the 1# unit profile with representative geological condition and 2# unit profile with comparatively complicated geological condition, the characters of stress, displacement vector and plastic zone of surrounding rock masses after excavation are analyzed. Some useful conclusions are gained. It will be significant for the construction of the project.
