摘要
Abstract
Taking Caijiacun Tunnel No.3 construction branch of Kunming section of Central Yunnan Water Diversion Project crossing the regional fault Xiaocang Yinchangqing Fault(F24)and crossing the left and right banks of the reservoir as an example,the"comprehensive method"advanced geological prediction method is used to scientifically and accurately predict the geological surrounding rock and groundwater conditions in front of the tunnel face.Advanced measures such as advanced water blocking grouting,advanced large pipe sheds,and advanced small conduits are used for advanced water blocking and reinforcement of surrounding rock.Advanced drilling is also used as drainage holes,and core soil is reserved for excavation and support in steps.Deformation is also reserved to ensure the safe and rapid passage of the fractured section of the inclined well rich water fault.关键词
