盾构穿越水平冻结加固区接收要点

Shield Crossing Horizontal Frozen Reinforced Area Receiving Points

在近年来的发展中,冻结法施工日益普遍,尤其在地下水丰富、地质条件差和环境复杂的情况下使用较多;现且多用于地铁隧道的联络通道和工作井位置。而冻结法施工的效果影响了工程的质量和隧道安全,通过对无锡地铁轨道交通工程3号线某站端头井盾构接收穿越冷冻区进行分析,为无锡地铁轨道交通建设提供经验和参考。

In recent years’ development, freezing method construction is becoming more and more common, especially in the case of rich groundwater, poor geological conditions and complex environment;now and mostly used in the contact channel and working well location of subway tunnel. The effect of freezing method construction affects the quality of the project and tunnel safety. By analyzing the shield receiving through the freezing zone in a station end well of Wuxi Metro Rail Transit Project Line 3, we provide experience and reference for Wuxi Metro Rail Transit Construction.
