摘要
利用数值分析的方法,详细讨论了水泥粉煤灰碎石桩(CFG桩)复合地基承载与变形特性;通过多种方案计算,就不同的荷载水平、桩长、置换率、桩土模量比、桩尖地质条件等因素,对桩土应力比的影响、桩土荷载分担规律进行了分析研究.
This paper discussed the bearing capacity and deformation behavior of CFG(cement fly-ash gravel)pile composite foundation with numerical analysis method. By comparison between different schemes computation, the pile-soil stress ratio and the loading distribution rule between pile and soil were analyzed, according to the effect of different load level, pile length, replacement ratio, soil layers and deformation modules of pile.
