摘要
城市地铁建设中,采用盾构法穿越淤泥质软土地层时,造成地面沉降较大,难以保证地面重要建筑物和设施的安全,同时也造成施工成本增加。本文从优化盾构推进参数和同步注浆等方面,就如何控制沉降进行了初步的探讨。
In the construction of urban subway, using the shield method to traverse mucky soil layer led to the bigger ground subsidence, and did＇t guarantee the safety of the important building and facility, also caused construction costs increasing. This paper from the optimizing shield thrusting parameters and synchronous grouting etc. discusses how to control the subsidence.
