摘　　要：针对连拱转大跨复杂工法环境下大跨横通道施工的重点难题,以苏州国际快速物流通道二期工程为背景,基于数值模拟,考虑隧道地质条件、施工工法和施工阶段等因素,模拟了双连拱转大跨复杂工法环境下大跨横通道施工开挖的全过程,并对隧道周围土体位移和应力分布进行了分析,验证了该工法的可行性和安全性。该研究成果可为同类工程施工提供参考。In response to the key challenges of large-span cross passages under the complex construction environment of multi arch to large-span,Phase Ⅱ project of Suzhou International Express Logistics Channel was taken as an example.Based on numerical simulation,considering factors of tunnel geological conditions,construction methods and construction stages,the entire excavation process of large-span cross passages under the complex construction environment of double arch to large-span was simulated.And the displacement and stress distribution of the surrounding soil were analyzed to verify the feasibility and safety of this construction method.The research results can provide reference for similar engineering construction.
