Analysis of TBM Construction Points for the Water Transfer Tunnel of the Western Water Diversion Project
TBM method has high requirements for geological conditions,and the strata in mountainous areas are often complex.During tunnel construction,sudden situations such as surrounding rock fragmentation,deformation,instability,collapse,water inflow,and rock burst are prone to occur.Taking the water transfer tunnel of the West Water Diversion Project in Anyang City of the South-to-North Water Diversion Project as an example,the unfavorable geological conditions of the tunnel construction process are analyzed inthis paper.The targeted countermeasures based on the site conditions and engineering experience are proposed.It can offer technical guidance for similar projects.
