摘　　要：针对我国黄土覆盖面广、分布厚度大、湿陷性严重,且在黄土软基上修筑公路和铁路工程增多的问题,在分析黄土中爆炸空腔特性的基础上,提出3个方面的填筑要求;对级配碎石、粉煤灰和化学固化剂等常用填料进行分类,提出级配碎石直接倾倒法、小型振捣设备配合填筑法和部分注浆法3种填筑工艺。According to the loess features of wide coverage, great thickness and serious collapsibility in our country and the problems of building more highways and railways on loess roadbed, after analyzing the characteristics of explosion cavity in loess roadbed, the paper proposes three filling requirements. It also classifies the common filling materials, such as grading gravel, coal ash, and chemical curing agent, and puts forward three filling technologies： dumping method with grading gravel, small vibrating equipment filling method and partial grouting method.
