摘要: 通过对某工程中软土地层盾构隧道联络通道的选位、冻结法地层加固、开挖等方面的分析,结合数值模拟计算,总结出联络通道设计和施工中控制工程风险的主要措施,并在工程应用中收到很好的效果。对今后软土地层类似工程的设计与施工具有一定的意义。Abstract: By means of analysing selection of the location of connected aisles from shield tunnels of a project in soft soil stratum,reinforcing the stratum by freezing method and excavating,etc,and carrying out the numerical simulation calculation,the main measures of controlling the construction risks from the connected aisle during design and construction were summarized. From which good effect was got in construction. It is of some guiding significance to the design and construction of similar projects in the soft soil strata in the future.
