摘要
分析了近年来工程建设中处理软弱地基的几种方法的利弊 ,介绍了基于灰土挤密桩和渣土桩而形成的孔内重锤夯实砂石桩处理软弱地基的施工方法 ,对采用孔内重锤夯实砂石桩法处理后的复合地基进行了原位静载荷试验、桩体超重型动力触探试验和桩间土标准贯入试验 ,通过检测 ,说明该方法有一定的实用和推广价值 .
This paper analyzes the advantages and disadvantages of means of foundation treatment in construction in recent years,introduces wecking ball ramming the grit-stone-pile in treating the soft foundation of the construction method between lime earth pile and residue earth pile.Then it has a static load testing,penetration test and standard penetration test.Its method is practical and can be used widely by test.
