Abstract
The western water transfer project of the South-to-North Water Diversion Project in Anyang City,traversing mountainous areas,is planned to use tunnel water transfer.The construction method is double shield TBM and drilling and blasting method.The main rock type in the project area is the limestone of the Majiagou Formation in the Middle Ordovician.The main engineering geological problems include the stability of the entrance slope,the stability of the shallow buried section surrounding rock,the problem of fault fracture zone,and the problem of karst development.Adverse geology affects the stability of the tunnel,and the risk of TBM jamming is high,which affects the safety of tunnel construction.The article analyzes and evaluates key geological issues in the engineering area,proposes reasonable treatment suggestions,and provides valuable reference for the survey,design,and construction of tunnels constructed using TBM.关键词
