湖相沉积软土在昆明地区分布广泛,工程性质极其特殊,在该场地中盾构施工风险性极高,易引发端头失稳,涌水涌砂灾害,探究软土场地盾构端头施工关键控制措施成为亟待解决的问题。采用经验分析法并引入正交试验对端头加固工艺及加固范围进行分析,得出适用性最优工艺与最优加固范围计算模型,给出各工艺应用建议、端头稳定敏感性排序及加固范围理论解。针对现有洞门密封止水系统涌水涌砂风险较大的问题,提出了一种由三道密封构件与两道主动措施组成的新型永久密封止水系统。将所得结论与创新型止水系统应用于昆明轨道交通5号线会宝区间端头,采用MidasGts与对数螺旋滑动计算模型对端头土体进行数值模拟与稳定性计算,所得位移云图及安全系数与实际施工情况相吻合,由此实现端头加固范围理论解与工程解的统一。从施工现场来看,新型止水系统应用效果非常理想,有效保证了盾构进出洞安全,可为相似盾构工程设计与施工提供借鉴。
Lacustrine sedimentary soft soil distributes widely in Kunming area, and its engineering properties are extremely special. In this site, the risk of shield construction is very high, which is easy to cause instability of the shield end and the disaster of water and sand gushing. Therefore, it has become an urgent problem to explore the key control measures for the construction of the shield end in soft soil sites. An empirical analysis method is used to analyze the end reinforcement process, and the orthogonal test is introduced to explore the reinforcement range, so as to obtain an applicable optimal calculation model. Therefore, the application suggestions of each process, the ranking of sensitivity of end stability and the theoretical solution of reinforcement range are given. In view of the great risk of water and sand gushing in the existing portal water sealing and stop system, a new permanent water sealing and stop system is proposed in this paper. This system consists of three sealing components and two active measures. The research conclusion and water stop system are applied to the end of Huibao section of Kunming Metro Line 5. Midas Gts and logarithmic spiral sliding calculation model are used to simulate and calculate the stability of the end soil. Calculated displacement contour and safety factors are consistent with the field measurement, achieving a unification of end reinforcement theoretical solution and engineering solution. From the construction site, the application effect of the new water stop system is very ideal, which effectively ensures the safety of shield entering and leaving the tunnel, and can provide a reference for the design and construction of similar shield projects.
