多年来,黄土的湿陷性和黄土地基的湿陷等级是用湿陷系数和分级湿陷量来评价的。在第五届国际工程地质会议(1986)上,苏联阿纳耶夫教授提出了一种评价黄土湿陷性的新方法,即湿陷势能法。苏联资料介绍,黄土在水的作用下,颗粒间连接减弱而向下移动,随而改变了原有的势能。势能改变所做的功,一部分以势能形式逸失,一部分则以热动势形式化为重新连接已饱和湿陷的黄土结构
Over the years, the collapsibility of loess and the collapsibility of loess foundations have been evaluated using collapsibility coefficients and graded collapsibility. At the Fifth International Conference on Engineering Geology (1986), Professor Anayev of the Soviet Union proposed a new method for evaluating the collapsibility of loess, namely the wet potential energy method. According to Soviet data, loess under the action of water, the interparticle connections weakened and moved downwards, which in turn changed the original potential energy. Some of the work done by potential energy changes is lost in the form of potential energy, and part of it is reformulated into a loess structure that reconnects saturated saturated depressions with thermal momentum.
