| 中文摘要:降水工程在地铁建设过程中具有举足轻重的作用，将直接影响地铁工程的工期及安全，对整个工程质量影响颇大。基坑开挖过程中很可能产生基坑底的突涌，引发安全事故。因此，施工前必须采取合理有效的地下水控制措施，防止土的渗透变形、突涌等不良作用对基坑边坡、底部造成影响，保证施工安全。管井降水是目前北京地铁工程降水中应用最广泛的一种方法。结合工程实例对管井降水的设计、施工及监测等一系列问题进行了研究。 |

| Abstract:Engineering dewatering is a decisive step in the process of subway construction, which has direct impacts on the duration and security of a subway project and influence of the quality of the entire project to a great extent. During the excavation, sudden inrushing is likely encountered; reasonable and effective control measures on groundwater must be taken to prevent the soil from infiltration deformation and inrushing to ensure construction safety. Tube well dewatering has been so far the most widely applied method in the subway construction projects in Beijing. Based on the engineering cases, the paper discussed a series of issues on tube well dewatering about the design, construction and monitoring, which can be referred by similar projects in future. |
