冲击碾压设备应用于软土换填工艺参数研究

摘要

为了进一步研究冲击压路机对换填土路基的作用效果，对压实次数、换填土厚度运用沉降差、压实度及标准差进行了表征，试验表明，在不同换填砂砾厚度下，存在较优的压实次数与之对应，并提出了合理的厚度压实次数参数，丰富了冲击碾压工艺，以供参考。%In order to further study the effect of impact compaction machine on the embankment,the compaction times,change the fill thickness by differential settlement,compaction degree and the standard deviation were characterized,tests showed that,in different replacement sand grav-el thickness,there is a corresponding compaction times better with the thickness,compaction times parameters reasonable,enrich the impact compaction process,for reference.
