湿陷性黄土桥头路段中的灰土挤密桩施工工艺

目前,在湿陷性黄土地区灰土挤密桩是最常见的地基处理措施。本文结合国道310三门峡西至豫陕界段南移新建工程,详细阐述了一种路基填土较高且沉降不满足要求的桥头路段中的灰土挤密桩施工工艺,本文的灰土挤密桩施工工艺可为类似工况提供参考。

At present, lime-soil compaction pile is the most common ground treatment measure in collapsible loess area. Combined with the newly built project of the section of National Road 310 from Sanmenxia to Yu-Shan to the south, this paper expounds in detail the construction technology of lime-soil compaction pile in the section of Qiaotou road with high subgrade f ill and its settlement does not meet the requirements. The construction technology of lime-soil compaction pile in this paper can provide reference for similar working conditions.
