摘要
在砂性土层中,联络通道的施工存在坍塌的风险,开挖前必须对周围土体进行加固,目前广泛采用的是冰冻法。结合武汉轨道交通2号线一期工程第十标段区间联络通道工程,对冰冻法施工过程中盐水温度及通道沉降监测数据进行分析,总结变化规律,提出相关建议。希望对今后类似工程起到借鉴和参考作用。
Collapse may happen in the construction of cross passage in sandy soil. So prior to the excavation, the surrounding soil must be consolidated. Freezing method is most widely used in soil consolidation. Combined with the cross passage project of the 10 th contract section of the first phase of Rail Transit Line 2 in Wuhan, the monitoring data of saline temperature and passage settlement during freezing construction were analyzed to get the change law. Suggestions are given to the similar projects for reference.
