摘要
夯扩桩克服了沉管灌注桩的承载力低、桩身质量难以控制等缺点 ,在桩端持力层埋深小于 2 0 0m的地区具有较好的适用性 ,能较大幅度地提高单桩承载力。
Temping expanding pile overcomes Some Shortcomings of cast in placepile,such as lower bearing capacity,difficult of pile body′s quality and so on.It has better applicability in such areas as the buried depth of holding layer is smaller than 20 meters,furthermore it may greatly inprove the beraing capacity of single pile.
