湿陷性黄土钻孔夯扩挤密桩填料试验研究

摘要

In order to find out the influence of different pile fillers on the nature and bearing ability of soil between piles in drilling-ramming-expanding pile composite foundation in collapsible loess, a spot testing and sample experiment on different fillers in soil between piles is carried out and the results show that different pile fillers have little influence on the compaction effect of the soil between piles and its bearing ability.%为探讨不同的桩体填料对湿陷性黄土钻孔夯扩挤密桩复合地基桩间土的性质及承载力的影响，通过对不同填料桩间土进行现场测试和取样试验，经试验结果显示不同的桩体填料对桩间土的挤密效果没有影响，对桩间土的承载力影响也不大。
