摘　　要：在地铁盾构隧道施工中,联络通道作为重要的结构部分,其施工安全与稳定性直接影响整个隧道的运行安全。地铁区间盾构与联络通道冻结同步施工技术是一种安全、有效、经济的施工方法,特别适用于复杂地质条件下的地铁隧道施工。采用冻结同步施工技术,可通过地层冻结形成高强度、封闭性好的冻土帷幕,防止管涌和流砂等地质灾害。本文通过实施冻结同步施工技术,成功实现了地层的有效加固和对地下水位的有效控制,防止了施工过程中的管涌和流砂现象。In the construction of subway shield tunnel,the contact passage is an important structural part,and its construction safety and stability directly affect the operation safety of the whole tunnel.The freezing synchronous construction technology of shield and contact channel in subway section is a safe,effective and economical construction method,which is especially suitable for subway tunnel construction under complex geological conditions.By using the freezing synchronous construction technology,high strength and good sealing frozen soil curtain can be formed through formation freezing to prevent geological disasters such as piping and sand flow.In this paper,through the implementation of freezing synchronous construction technology,the formation is effectively strengthened and the groundwater level is effectively controlled,and the phenomenon of piping and sand flow in the construction process is prevented.
