摘要
对大伙房水库引水隧洞TBM机安装段主洞和辅洞交叉部位进行了三维数值模拟。计算了围岩的应力场和位移场及破坏区域,并对围岩的稳定性进行了评价。对大型隧洞工程的设计和施工具有指导意义。
Three-dimensional numerical simulation is made at the cross position of main tunnel and assist tunnel at TBM machine installation section in diversion tunnel of Dahuofang reservoir. The stress field and displacement field and broken area of surrounding rock are calculated , the stability of surrounding rock is estimated. Have the guidance meaning to the design and construction of large-scale tunnel project.
