某大面积真空预压工程的几个问题浅析

Simply Analysis of Vacuum Preloading Project Applied to a Large Area

上海某大面积场地形成工程采用真空预压手段分块进行地基处理,在真空预压过程中,分别对各地块的地表沉降和土体分层沉降进行了跟踪监测,得到了一些有用数据。论文结合勘察报告、施工流程以及现场监测数据等,对真空预压对周边环境的影响、相邻真空预压地块在施工过程中的相互影响、土体的压缩和回弹等几个问题进行了综合分析,得出了一些有益结论,为今后类似工程的施工提供了参考。

There is a certain large area in Shanghai, which use the vacuum preloading method to do the block foundation treatment. During the whole progress, we check and monitor the ground surface settlement, layered settlement of the land,respectively and get some useful data.Base on the geotechnical report, construction process and on-site testing data,it is analysised vacuum preloading effection to the srroundings and the construction interaction effection to the adjacent blocks,soil compression and rebound,finally get some useful conclusion.,this could be the model for the subsequent construction.
