中文摘要	通过不同的室内试验,对风积沙的压实特性、压实原理以及工程特性和特点进行分析,提出适合毛乌素沙漠地区风积沙路基的干压法施工工艺与湿压法施工工艺,以及较为合理的机械组合与压实参数。研究结果表明:在干燥状态和最优含水率状态下,风积沙都可被压实,最佳振动频率均为44 Hz;风积沙达到最大干密度在冲击振动工况下比纯振动工况下所用时间短,并且最大干密度更大;与1次填料方式相比,采取多次填料方式减小风积沙的松铺厚度,每层控制在50~60 cm,可获得较大的压实度。
英文摘要	The compaction characteristics, compaction principle and engineering properties of aeolian sands were analyzed by different laboratory tests. Dry pressing method, wet pressing method and its reasonable machinery combination and compaction parameters were proposed for the aeolian sand roadbed in Mu Us Desert. The results show that: Aeolian sand can be well compacted and its best vibration frequency is 44Hz whatever it was in the dry state or in optimum moisture condition. Aeolion in the shock and vibration condition would get greater dry density in shorter time than those only in vibration condition. Comparing with packing method in one time, greater degree of compaction would be obtained by loosing laying thickness of aeolian sand which was controlled at 60~80 cm in multiple ways.
