摘　　要：上海某盾构隧道工程进洞施工地质和周边环境复杂,施工技术风险高,该工程上下行线地基加固采取了不同的水泥系和冻结法相结合的综合加固方式。针对上下行线分别介绍施工过程中主要技术要点,对过程中发现的问题进行了对比分析,进行了经验总结。The tunneling-in construction geology and the surrounding environment of a shield tunnel project are complicated in Shanghai, and its construction technical risk is high. The different composite reinforcement methods combined with the cement system and freezing method are used to reinforce the subgrades at the uplink and the downlink of this project. Aiming at the uplink and the downlink, the article separately introduces the main technical gist in the construction, compares and analyzes the problems found in the process, and summarizes the experience.
