地下车站复杂地层中降水施工分析

ANALYSIS OF DEWATERING CONSTRUCTION OF UNDERGROUND STATION IN COMPLEX FORMATION

结合工程实践,围绕多种基坑降水方式相结合的方案展开降水分析。实践表明,采用该方案可有效解决粉土夹粉砂及夹层等复杂地层中深基坑降水施工难度大的问题,可在无水条件下组织深基坑的建设工作,在保证深基坑主体施工安全质量的同时,尽量减少对周边建筑物、道路、管线等的影响。

Based on engineering practice,dewatering analysis was conducted in conjunction with a combination of foundation pit dewatering schemes.Engineering practice has shown that this can effectively solve the problem of significant difficulty in deep foundation pit dewatering in complex formations such as silty sand layers and interlayer.Foundation pit construction can be organized in the absence of water,to ensure the safety and quality of main works of deep foundation pits while minimizing the impact on surrounding buildings,roads,pipelines,etc.
