摘　　要：常规的风积土击实试验通常是在不考虑其他影响因素的情况下,研究土体含水量对干密度的影响。为保证风积土体的压实效果,文章综合考虑可能影响风积土体干密度的重要因素,即风积土原始含水量、最终击实含水量、分层铺筑厚度、击实做功大小和重复击实循环次数。对上述影响因素进行耦合,开展风积土体击实试验,通过极差分析方法研究各因素对风积土体干密度的影响程度和影响规律,以期为工程施工提供参考。The influence of the moisture content of soil mass on the dry density is generally studied by the conventional aeolian soil compaction test without considering other influencing factors.In order to ensure the compaction effect of aeolian soil mass,important factors that may influence the dry density of aeolian soil mass are comprehensively considered,namely:the original moisture content of aeolian soil,the final compacted moisture content,the thickness of layered paving,the size of compacted work,and the number of repeated compaction cycles.The coupling on the above influencing factors is made,the compaction test on the aeolian soil mass is carried out,and the degree and law of influence of each factor on the dry density of aeolian soil mass are studied through the range analysis method,so as to provide reference for the engineering construction.
