摘　　要：我国是全世界黄土占比面积最大的国家,黄土分布区域广的地方因为其松散、多孔隙、明显的垂直节理的特点而频繁发生剥落、侵蚀甚至坍塌事故,容易造成人员伤亡、财产损失,甚至会给当地的经济发展带来不利影响。文章首先梳理了黄土的基本概念,基于黄土的基本特性,通过总结黄土引发的灾害以及影响,阐述了研究的意义。根据黄土湿载变形的研究现状,对未来在湿载作用下的黄土力学特性研究做出了展望,指出今后要重视此类问题的研究。Our country is the largest country in the world with loess proportion of area. In places with wide loess distribution area, because of its loose, porous and obvious vertical joints, peeling, erosion and even collapse accidents frequently occur, it is easy to cause casualties, property losses, and even adverse effects to the local economic development. This paper first sorts out the basic concept of loess, based on the basic characteristics of loess, through summarizing the disaster caused by loess and its impact, expounds the significance of the research. According to the research status of loess deformation under wet load, the future study of loess mechanical properties under wet load is prospected, and it is pointed out that more attention should be paid to the study of such problems in the future.
