摘要
在人口密集的大型城市施工地铁车站,基坑降水对周边环境影响范围广、持续时间长且通常结果不可逆。通过分析研究位于某市建城区内一座具有代表性的地铁车站基坑降水项目,为后续类似项目的设计与施工管理提供极有价值的参考依据与实践经验。由于水文地质条件复杂,地下水储量丰富且水头压力大,科学合理的基坑降水设计方案、精细化的施工管理与及时有效的险情处理措施是保障车站主体结构安全施工的关键。
In the construction of subway stations in densely populated large cities,the influence of foundation pit dewatering on the surrounding environment is extensive and lasting for a long time,and usually the result is irreversible.In this paper,a representative subway station foundation pit dewatering project located in the city is analyzed and studied.It provides valuable reference and practical experience for the design and construction management of similar projects. Because of the complex hydrogeological conditions in city,abundant groundwater reserves and large head pressure,scientific and reasonable design scheme of foundation pit precipitation,fine construction management and timely and effective risk treatment are the key to ensure the safe construction of the main structure of the station.
