| Abstract: | Double shield TBM was adopted mainly in the tunnel construction of Diversion of Datonghe River to Huangshuihe River.When the tunnel crossed deep buried regional fracture zone,detouring drift method and drilling and blasting method were used for the tunnel construction.The surrounding rock deformation was analyzed in the paper,and the time effect of surrounding rock deformation during tunnel excavation was pointed out,which could provide theoretical basis for design and construction. |
