摘要
以天津地铁某区间端头井冻结加固工程为例,针对工程中存在的埋深大、地质条件差、洞门结构漏水、接收端上临建构筑物、工期紧、与明洞交叉施工等问题,分析了冻结施工中存在的风险,并提出了应对措施,保障盾构始发与接收顺利完成,可为类似工程施工提供参考。
Taking the freezing and strengthening project of a section end well of Tianjin metro as an example,in view of the problems existing in the project,such as large buried depth,poor geological conditions,water leakage in the structure of the tunnel portal,temporary structures on the receiving end,tight construction schedule,and cross construction with the open tunnel,etc.,this paper analyzes on the risks existing in the freezing construction,and advances some corresponding measures to ensure the smooth completion of the launching and receiving of the shield,which can provide references for similar projects.
