邻江特大异型基坑降水与基坑变形关系研究

摘要

以上海市紧邻黄浦江的渔人码头特大异型超深基坑工程为背景,采用基于弹性理论的基坑降水计算方法,探讨了基坑降水对周围环境的影响;计算了考虑降水和不考虑降水两种情况下基坑开挖导致的沉降差异,并以基坑周围建筑物和管线为例做了对比分析,研究结论可为今后类似工程提供有益的指导。%Taking the super-large allotype ultra-deep foundation pit at Yuren wharf near Huangpu River in Shanghai as the background,the paper adopts the foundation pit dewatering calculation method based on the elastic theory,explores the influence of the foundation pit dewatering on surrounding environment,calculates the settlement differences caused by the foundation pit excavation in the consideration with and without dewatering,compares and analyzes the surrounding buildings of the foundation pit and the pipelines,so the conclusion can be referred by similar projects in future.
