摘　　要：盾构的始发与接收是大直径盾构隧道工程施工中的关键工序,具有施工难度大、风险高的特点,如何安全顺利地完成盾构接收,一直是盾构法隧道工程亟需解决的难题之一。文中以杭州博奥隧道工程为例,对在粉砂土层地质条件下大型泥水平衡盾构的接收方案及施工控制关键技术进行了分析,为今后同类型地质条件下大型泥水盾构接收提供参考。The starting and receiving of shields are the key processes in the construction of large-diameter shield tunnels, which are characterized by high construction difficulty and high risks. How to safely and smoothly complete the receiving of shields has always been an urgent problem for shield tunneling projects. one of the problems. Taking Hangzhou Boao Tunnel Project as an example, this paper analyzes the receiving scheme and key construction control technology of large-scale mud-water balance shield under the geological conditions of silt soil layer, and provides a reference for the reception of large-scale mud-water shield under the same type of geological conditions in the future.
