    NUMERICAL ANALYSIS WITH FLAC~(3D) ON ROCK MASS STABILITY SURROUNDING CAVERN GROUP IN THE LEFT BANK SLOPE OF A HYDROPOWER STATION ON LAN-CANG-JIANG RIVER

    • 摘要: 在岩体结构模型概化的基础上,采用FLAC3D数值分析方法,系统研究了澜沧江某大型水电站大跨度、高边墙地下洞室群开挖完成后围岩的二次应力场、变形场和塑性破坏区的变化特征。总结了地下洞室群围岩应力、变形和破坏区的分布特征和变化规律,为洞室群稳定性评价和工程施工设计提供了基础资料和参考依据。

       

      Abstract: Based on the simplified structure of rock mass,FLAC~(3D) numerical modeling technique is used to systematically analyze the distribution features of the secondary stress field,strain field and plastic zones in the surrounding rock mass of the underground cavities after the excavation.And the variation characteristics of stress field,strain field and plastic failure zones in the surrounding rock mass of the underground cavities are summarized,which provides basic information and reference for the evaluation of underground cavities stability and project construction.
