摘　　要：依托深圳市城市轨道交通16号线二期工程共建综合管廊工程,建立富水软弱地层盾构始发加固设计方法。基于修正剑桥模型的极限平衡理论,推导富水地层加固范围计算公式,并通过现场实测对加固设计方法进行验证,最终形成富水软弱地层综合管廊盾构始发加固技术。Based on the comprehensive pipe gallery project jointly built by the second phase project of Shenzhen urban rail transit line 16,the paper establishes the design method of shield launching reinforcement in water rich soft stratum.Based on the limit equilibrium theory of modified Cambridge model,the calculation formula of reinforcement range of water rich stratum is deduced,and the reinforcement design method is verified through field measurement,and finally the starting reinforcement technology of comprehensive pipe gallery shield in water rich soft stratum is formed.
