大面积、超补偿的干坞地基变形研究——上海外环隧道的浦东干坞开挖工程

A study on deformation of soil for large area and over-compensated foundation in dry-dock excavation engineering——Dry dock excavation engineering of outer Ring Tunnel Project in Pudong, Shanghai

摘要: 对一个大型干坞沉管制作的珍贵沉降监测资料进行分析,同时,运用20多年来对回弹与再压缩研究成果,采用综合分析方法,从不同角度分析,进一步运用有关理论与经验的综合,对本课题进行深入分析,得出有益的结论,以期填补上海地区该类岩土工程问题的空白,为类似工程积累宝贵的经验。

Abstract: The measured settlement data of a large dry-dock were analyzed in detail.Based on the research results for soil swelling and recompression accumulated in more than 20 years,the synthetic analysis method was adopted.From several different points of view and with comprehension of relevant theory and experience,some beneficial and useful conclusions has been obtained,which can be used to solve geotechnical problem in Shanghai for similar projects.
