浅覆土盾构下穿人行通道施工研究与应用

Study and application on construction of pedestrian tunnel under shallow earth shield

为应对复杂环境下的盾构下穿作业,对深圳地铁9号线盾构下穿兰溪谷人行通道进行了研究分析,采用统计对比的方法,验证了浅覆土盾构下穿参数的有效性,以期对广深地区类似工程有一定借鉴作用。

In order to cope with the operation of shield tunneling in complex environment, the passage through Lanxi valley under shield on Shenzhen metro line 9 is studied and analyzed. The validity of the parameters under shield tunneling is verified by statistical comparison method. It can be used for reference to similar projects in Guangzhou-Shenzhen area.
