灰土井桩作为一种柔性桩其工作特性与普通刚性桩存在较大差异,桩型的影响十分明显,本文继异形灰土井桩现场足尺试验后,分析研究了灰土井桩桩型效应的产生机理,指出圆楔形桩是一种较优桩型,这种桩型改善了灰土井桩承载力较小,沉降较大的问题,是一种在不增加地基基础工程量及投资情况下,提高灰土井桩承载力的行之有效的方法.
As a kind of flexible pile, the characteristics of lime-dwell piles are quite different from those of ordinary rigid piles. The influence of pile type is very obvious. After the full-scale test of irregular lime-soil piles in the field, the pile-type effect of lime-dwell piles is analyzed and studied. The mechanism indicates that the circular wedge-shaped pile is a better type of pile. This kind of pile type improves the problem that the lime soil shaft pile has a smaller bearing capacity and a larger settlement, which is an increase without increasing the foundation engineering amount and investment of the foundation. Lime pile bearing capacity of the effective method.
