湿陷性黄土地区灰土挤密桩处理涵洞地基效果研究

On treatment effect of culvert foundation with lime-soil compaction pile in collapsible loess areas

结合湿陷性黄土地区某工程实例,介绍了灰土挤密桩处理涵洞地基的试桩方案,并从承载力与挤密效果两方面,分析了其地基处理效果,指出灰土挤密桩可有效消除黄土的湿陷性,达到地基处理规范和设计的要求。

Combining with some project in the collapsible loess areas, introduces the trial pile scheme for the treatment of culvert foundation with the lime-soil compaction pile, analyzes its foundation treatment effect from the loading capacity and compaction effect, points out the lime-soil compaction pile can effectively eliminate the collapsibility of the loess and achieve the regulation and demands for the foundation treatment.
