摘要
本文介绍了用水泥-土搅拌桩形成的拱形槽壁支护结构的研究和应用。这是一种既能挡土又能挡水且位移很小的支护方式,在国内外尚无先例。该方法在上海市江苏路泵站的排水总管埋设(挖深9m)施工中首次应用并获得了成功。这种支护结构比地下连续墙经济得多,值得推广应用。本文还介绍了在该工程中取得的测试结果,为设计与施工提供了有价值的依据。
A new technique of retaining structure——Arch Trough Retaining Wall formed by mixed cement-soil
piles is introduced. It can retain both earth and water, with small displacement. It was used firstly at home and abroad. This method was applied in a drainage main of Jiangsu Road Pumping Station, Shanghai. The depth of excavation is 9 m. And its cost is much less than the continuous concrete wall. Therefore, it is deserved to recommend this structure. Some measurements from this project are also presented. They should be useful for design and construction.
