摘要
Abstract
The paper takes the Biling Tunnel of the Dongjiang Water Source Project in the Anliang Station to Xikeng Station section of Shenzhen Urban Rail Transit Line 16 Phase Ⅱ as the research object.Based on a comprehensive analysis of the construction environment,shield tunneling method was adopted for construction,and steel plates are used to reinforce the inner lining of the tunnel defects.MidaT was used for excavation simulation analysis of the Biling Tunnel section,and two-dimensional mechanical analysis was conducted using Lizheng software.The maximum vertical settlement displacement value of the water supply tunnel was found to be 0.68mm,which is lower than the limit requirement of 10mm additional vertical displacement during the operation period in relevant specifications.Based on this,water supply safety analysis was carried out.关键词
