摘要
武汉长江隧道位于武汉地区特殊的上软下硬且承压水位高的地层中,采用地下连续墙法施工,由于地质条件复杂,成槽技术是施工的关键。施工中通过采取改善泥浆性能、提高液面和设备优化组合等一系列有效的技术措施,减少了坍孔和周边环境的影响,确保了成槽精度和墙体质量。所取得的经验对类似工程有参考价值。
Wuhan Yangtze River tunnel is embedded in a two - layered stratum with soft upper and hard lower layers and with confined underground water with high water head. The tunnel is built by adopting underground diaphragro walls. To build underground diaphragm walls in this area the technology of trenching is crucial. In the process of trenching some measures were adopted such as: mud of allocated proportion, liquid level controlling, equipment optimization and combination and so on, as a result, the efficiency of construction was improved, the possibility of collapse and the environmental effect were decreased, the trench precision and the quality of the walls were ensured.
