回填碾压地基的CFG桩加固工程

CFG Pile Consolidation for Backfill Rolling Compacted Foundation

摘要:

针对回填碾压地层条件，选择高置换率CFG桩复合地基方案进行地基处理。利用合理的复合地基构造形式，改善其受力特性，充分发挥桩体和桩间土的承载能力，达到了提高地基承载力、减少地基沉降的工程效果，取得了良好的经济技术效益。

Abstract:

According to the conditions of backfill rolling compacted foundation, CFG pile composite foundation with high replacement ratio was selected. With the rational structure form of composite foundation, the mechanical characteristics were improved for obtaining full bearing capacity of the pile and the soil between piles to increase the capacity of the foundation and reduce the foundation settlement.
