孔内夯扩挤密桩在湿陷性黄土地区的应用

Application of In-hole Rammed Extrusion Piling in Hydrocompactible Loess Area

以巩义某电厂冷却塔桩基施工为例,采用了孔内夯扩挤密桩,解决了复杂地质条件下的疑难地基处理问题,有效地消除了黄土的湿陷性,提高了地基的承载力,得了良好的施工效果,可为相似地质条件下的地基处理提供参考。

Take a cooling tower piling foundation engineering of a power plant in Gongyi City as an example. An in-hole rammed extrusion piled foundation, has overcame difficult foundation management under complicated geological condition. It has kept away from loess hydrocompactibility with advantage, raised foundation carrying capacity, and acquired good operating effect. It offered a reference to foundation management under similar geological condition.
