盖挖主基坑内明挖二级基坑变形与渗流分析

摘要

本文通过理论数据模型计算，对盖挖主基坑条件下进行二级基坑降水和开挖施工，进行了基坑稳定变形和渗流分析，并结合现场工程实践验证了相应安全、质量保证措施的有效性。%Through the theoretical data model calculation, the cover excavation of foundation pit under the conditions of the two main foundation pit dewatering and excavation. This paper analyses stability deformation and seepage on foundation pit, and verificates to the relevant safety and quality assurance measures based on the engineering practice.
