Collapsible soils are known to experience significant volume decreases due to an increase in moisture content, regardless of a load increase. This in turn causes the design of foundations on collapsible soils to be highly problematic. Soils susceptible to collapse include loess, cemented sand and silts, and some residual soils. Collapsible soils are found in major parts of Eastern and Western Canada, USA, Eastern Europe, China, South East Asia, and both Northern and Southern Africa. As human activities continue to increase in these regions, the problems associated to foundation design increase accordingly (Brandon et al., 1990; Lim and Miller, 2004).

众所周知，无论负载如何增加，湿陷性土壤都会因含水量的增加而经历显着的体积减小。这反过来又导致湿陷性土壤上的地基设计存在很大问题。易塌陷的土壤包括黄土、胶结砂和粉土，以及一些残余土壤。湿陷性土壤分布于加拿大东部和西部、美国、东欧、中国、东南亚以及非洲北部和南部的主要地区。随着这些地区人类活动的不断增加，与基础设计相关的问题也相应增加（Brandon等，1990；Lim和Miller，2004）。
