摘要
在富水砂层中采用土压平衡盾构下穿河流及既有建筑物施工,具有较大的风险和难点。结合北京地铁6号线工程土压平衡盾构施工的成功实例,从盾构机设备的性能配置、施工工艺参数(掘进参数)、辅助措施(渣土改良)等方面,分析、论证了在富水砂层中采用土压平衡盾构机掘进施工的关键技术。
Using EPB shield in the water-rich sands through rivers and undercrossing existing buildings has great risks and difficulties. This paper combining with successful examples of Beijing subway line six with EPB shield,the key construction technology is introduced from the shield performance configuration,construction process parameters( driving parameters)and supporting measures( ballast soil improvement).
