摘要
根据地质探洞揭露的厂房区域地质资料,建立三维数值计算模型,进行地应力反演和围岩稳定计算。通过对围岩的变形、塑性区和应力特征进行分析,对地下厂房洞室群围岩的三维整体稳定进行分析评价。
The underground workshop caverns of Fujian Yunxiao Pumped storage Power Station are large in scale and complicated in layout.In this paper,based on the regional geological data of the workshop revealed by geological exploration,a three-dimensional numerical model is established to carry out ground stress inversion and surrounding rock stability calculation.By analyzing the deformation,plastic zone and stress characteristics of surrounding rock,the three-dimensional stability analysis and evaluation of surrounding rock of underground powerhouse caverns group are made.
