CFG桩与夯实水泥土桩多元复合地基的应用研究

介绍了CFG桩和夯实水泥土桩多元复合地基在洛阳某重机加工车间的应用情况，通过CFG桩单桩、夯实水泥土桩单桩及复合地基载荷试验结果分析，证明了地基处理方法的适用性。同时，对复合地基中桩及桩间土的应力比进行了分析，提出了桩及桩间土承载力的变化特征。

Study on Application of Multi-element Composite Foundation of CFG Pile and Rammed Soil-cement Pile

This paper introduced the application of multi-element composite foundation of CFG pile and rammed soil-cement pile in certain heavy machinery fabricating workshop in Luoyang.Through analysis of the results of the load tests in relation to single CFG pile，single rammed soil-cement pile and the composite foundation，the applicability of this treatment was proved.Meanwhile，the ratio of stresses in the piles and the soil between piles was analyzed with the change features of bearing capacity of the piles and the soil put forward.
