【摘要】 通过对复合地基原体试验检测成果的分析 ,验证了碎石桩加密效果的规律。对于利用载荷试验成果确定碎石桩复合地基承载力的方法 ,进行了深入的理论分析和探讨 ,提出了对于碎石桩复合地基s/b的取值 ,不单要考虑岩性 ,同时要结合复合地基的含水量和饱和度 ,来更加准确的确定s/b的取值。建议对已排水疏干的碎石桩地基 ,s/b的取值应趋近干法施工的其他挤密桩之值。更多还原

【Abstract】 Prototype testing of vibro replacement ston colume me thod ground treatment is very important.The paper analyze the result of test,rule of reinforce is proved.The paper analyze the use result of plate loading test to confirm bearing capacity of composite foundation in theory,Advancing that the radio of s/b is taken into account not only lithology but also content water and degree of saturation,for more exact to confirm the ratio of s/b.we suggest that the ratio of s/b ought to approach ratio of s/b compaction pile when the water of virbroflotation ground had drained and depleted.更多还原
