中文摘要：
介绍了一种新型的地基处理方法——混凝土芯砂石桩复合地基法及其在水利防洪堤软基加固工程中的应用情况。通过现场原位观测和试验,研究了混凝土芯砂石桩复合地基固结变形、孔压消散、桩土应力分担及承载力特性,结果表明混凝土芯砂石桩强度高,排水固结能力强,能迅速提高桩间土强度和承载力,应用于水利堤防工程既能控制堤防深厚软基的工后沉降,又能提高堤防边坡的稳定性,推广应用前景良好。
英文摘要：
It was introduced as a new ground treatment method that the composite foundation method named with concrete-cored sand-gravel piles was applied to the embankment strengthening.Based on in-situ observation and testing,the consolidation settlement,the pore water pressure,the pile-soil stress ratio and the bearing capacity is investigated.The results indicated that the strength of the concrete-cored sand-gravel pile was high and the effect of drainage-consolidation was obvious.Furthermore,the strength and bear...
