摘要
通过对西北地区常规桩距、桩径等参数的调整,并结合工程实例进行验证,确认了三七灰土作为桩身材料、桩径500 mm、桩距1.30 m的工艺参数能有效消除黄土湿陷性,复合地基承载力特征值可达210 k Pa,该法较常规灰土挤密桩工艺参数具有更高的经济性。
Through the regular spacing in the Northwest,diameter parameter can be adjusted,and validated by the project,identified 3∶ 7 limesoil compaction pile material,diameter 500 mm,distance 1. 30 m parameters can eliminate collapsibility of loess,characteristic value of bearing capacity of composite foundation of 210 k Pa,this method than the conventional parameters of lime-soil compaction pile with higher efficiency.
