摘　　要：新近堆积黄土分布于浅层地表,多以持力层存在,但工程性质与一般湿陷性黄土有差异。确切掌握新近堆积黄土的工程特性,可以在实际工程中针对新近堆积黄土采取有效的处理措施,避免工程事故。总结了目前关于新近堆积黄土在判别方法、工程特性和地基处理等三方面的研究进展情况,并结合其中的不足提出了相应的研究展望。The newlyaccumulated loess is distributed in the shallow surface,and is mostly existing in the holding layer,but the engineering property is different from the general collapsible loess.In order to avoid engineering accidents, we can take effective measures to deal with the newly accumulated loess in actual engineering.In this paper,we summarize the progress of the recently accumulated,loess in the three aspects of discriminant method,engineering characteristic and foundation treatment,and analyzes the advantages and disadvantages of them,finally put forward the outlook for the next phase of the study.
