深基坑全逆作法施工技术在软土地区的应用

Application on Construction Technologies with Reverse Method of Deep Foundation Pit in Soft Soil Area

介绍了某软土区深基坑全逆作法施工中总体设计方案的选取、地下连续墙、土方开挖等施工工艺。施工中通过采用全逆作法的施工方案,在场地狭小、对周围相邻建筑保护和管线保护要求较高的情况下,大大缩短了工期,满足工程进度要求,较好地达到了预期目标。

The construction, technologies with reverse method of deep foundation pit in some soft soil area are introduced, such as the overall design plan selection, underground diaphragm wall, earth excavation, etc.. Through the construction scheme of total reverse method, it can achieve a better target in small venues and higher requirements of the adjacent building protection and pipeline protection conditions, which can shorten working time and meet the requirements of project progress.
