摘要
石太客运专线DK97＋123.8~DK106＋663段线路位于湿陷性黄土地区,该湿陷性黄土为Ⅰ级非自重湿陷性场地。为确保该段湿陷性黄土路基的稳定性,在分析冲击式压路机处理湿陷性黄土地基的工作原理基础上确定了工程施工技术参数及施工方案,跟踪施工进行的湿陷性黄土地基处理效果的检测表明,处置技术保证了碾压下面1 m深度范围内的土的压实度达到了不低于90%,湿陷性系数小于0.015的处理效果。
DK97＋123.8~DK106＋663 section of Shijiazhuang Taiyuan Passenger Dedicated Line line in collapsible loess area,it is grade I- site of self weight collapsible loess. In order to ensure the stability of the collapsible loess roadbed, according to the analysis of impact roller in collapsible loess foundation treatment, determine the working principle of the construction technical parameters and construction scheme, show that the detection of collapsible loess foundation treatment effect of track construction, disposal technology to ensure the rolling below 1m depth with in the scope of the soil compaction was not less than 90%, the treatment effect of collapsible coefficient is less than 0.015.
