摘要
文中以深圳某隧道建设项目为依托,对大直径盾构靠近既有结构隔离循环保压注浆技术进行了分析,并对施工后既有结构的变形进行监测,分析隔离循环保压注浆技术的效益,以保障隧道盾构施工过程中既有结构的安全.
Abstract
Based on a tunnel construction project in Shenzhen,this paper analyzes the isolated circulating pressure retaining grouting technology of large diameter shield near the existing structure,monitors the deformation of the existing structure after construction,and analyzes the benefits of isolated circulating pressure retaining grouting technology to ensure the safety of the existing structure during the tunnel shield construction.
