载体桩在北京宏福大厦工程复合地基中的应用

Application of Ram-compacted Piles with Bearing Base in Composite Foundation of Beijing Hongfu Building

将载体桩工艺作为复合地基增强体应用于复合地基的施工,由于载体桩承载力高而大大提高复合地基承载力,且由于大部分荷载通过载体桩传递到了深层土体,故载体桩复合地基沉降也大大减少。本文以一工程实例介绍该技术的设计、施工、检测,供同行参考。

Ram-compacted piles with bearing base is constructed in the composite foundation as the reinforcement pile, because the bearing capacity of ram-compacted piles with bearing base is higher than ordinary pile,the bearing capacity of composite foundation constructed by ram-compacted piles with bearing base increases,and because most of the load is transferred to the deep soil by the pile,the settlement decreases.The designing,construction and testing of a real engineering are introduced,so that it supplies the reference to technicist in the same field.
