盾构隧道穿越软土地层技术研究

Research on Shield Tunnel Crossing Soft Soil Layer

文章依托工程实例,结合工程特点综合考虑位于软土地层范围盾构隧道的施工及运营期间风险,软土地层分布情况及周边环境因数,从隧道设计阶段及施工阶段盾构机选型两方面处理措施进行了研究。

Based on the engineering examples and combined with the characteristics of the project,the article comprehensively considers the risk during the construction and operation of the shield tunnel located in the soft soil layer,the distribution of the soft soil layer and the surrounding environmental factors,and this paper studies two measures of the selection of the shield machine from the tunnel in construction stage and design stage.
