学科：工程地质学 词目：溶陷性 英文：thaw collapsibility 释文：溶陷性是盐渍土浸水后由于盐晶溶解或侵蚀作用产生沉陷的性质。一般是易溶盐的含盐量越高、土的渗透系数越大的盐渍土溶陷性越强。
试验结果表明：板块状盐渍土属溶陷性土，随着含盐量的增大，溶陷系数增大；
The results show that the plate-like saline soil is collapsible soil, and the coefficient of collapsibility increases with the increase of the salinity.
本文提供了一种根据盐渍土含盐量及洗盐后土的干重度判别盐渍土是否具有溶陷性的简易方法，从而可以避免进行室内外的溶陷性试验。
A simple method to determine whether the saline is collapsible based on its salinity and dry unit weight is proposed herein, so the collapsibility tests in laboratory or at field may be saved.
湿陷性黄土地基浸水饱和后，由于易溶盐类的溶解，土结构的破坏，使其承载力直线下降。
When the basement of collapsible loess is saturated by water, the earth structure is damaged due to the resolution of soluble salt, which causes the reduction of its bearing capacity.
