南通地区粉砂地基水泥土搅拌桩围护工程的成功经验

Succedging Experience of Supportment Engnieering By Using Soil-Cement Mixed Pile in Silt Soil at Nan Tong

本文介绍了南通市金信大厦开挖深度为6.75m的深基坑,在粉砂地基上采用水泥土搅拌桩—井点降水复合型的围护结构,既保证了周围建筑物和道路管网的安全,又节约了工程费用,为在南通市及其它类似地质条件的深基工程提供了典型工程实例。

In this article, a deep excavation with depth 6. 75m of JingXia building is introduced. Composite supported structure was used by soil-cement mixed pile-well point dewater in siltsoil. It can not only ensure surrounding buildings, road and pipe system, but also supply a typecal example for deep excavation engineering at NanTong and other similar geology condition area.
