地铁暗挖法施工中降水引起地面沉降问题的探讨OA
Discussion on the Ground Subsidence Caused by Precipitation during Subway Excavation Construction
近年来，地铁暗挖施工中辅助降水措施取得了很大成功，但由降水引起的地面沉降，其成因、危害性、如何避免和控制是十分重要的问题。本文结合北京地铁7号线双井站工程实际经验，对降水沉降问题进行探讨和总结。车站主体暗挖施工过程中，监测降水沉降值仅4.0mm，证明双井站降水方案和沉降控制措施是合理的。
In recent years, the assistant precipitation measures during the subway construction has achieved great success. However, the ground subsidence caused by precipitation, and how to avoid and control is a very important problem. In this paper, combined with the engineering practical experience of the Beijing Shuangjing Station on Line 7, the problems of dewatering and settlement are discussed and summarized. During the station excavation construction process, …查看全部>>
