【摘要】 常用的水泥土搅拌桩复合地基和挡土墙在软土地基加固和基坑围护工程中普遍应用 ,但是水泥土搅拌桩的强度较低 ,因此承载能力不高。加芯水泥土搅拌桩以预制的钢筋混凝土小桩作为核心 ,插入水泥土搅拌桩中形成复合桩 ,使其获得较高的承载力 ,而且没有打入桩的噪音和挤土 ,没有钻孔灌注浆的泥浆污染 ,是一种经济效益和社会效益较高的新桩型。更多还原

【Abstract】 Soil cement mixing pile has been used on soft soil foundation treatment and foundation pit bracing,however,the strength of soil cement mixing pile is low and its bearing capacity is not high.For soil cement mixing pile with concrete pile,there is larger bearing capacity,there is not noise and soil compaction like driven pile,and not mud pollution like cast in place pile,so it is a kind of new pile having economical and social profit.更多还原
