摘要
针对杭州某地铁隧道联络通道地质条件复杂、埋深大、上部临江等特点,分析了砾石地层冻结孔施工、冻结施工及冻结孔割除过程中的风险,并提出了相应的应对措施,为类似工程施工提供了参考。
Based on such characteristics of connecting passage in Hangzhou metro tunnel as complex geological condition,large buried depth and river crossing,construction risk of freezing holes,freezing and freezing hole removing are discussed,and corresponding countermeasures are suggested as well,providing useful reference for similar project construction.
