Collapsible soils are known to experience significant volume decreases due to an increase in moisture content, causing foundation to sink in the ground, which further damages the building and reduce its serviceability. Collapsible soils form large parts of Eastern and Western Canada, the United States, Eastern Europe, China, South East Asia, and Northern and Southern Africa. As the human activities continue to increase in these regions, geotechnical engineers must learn how to deal with this difficult soil. Soils susceptible to collapse include: loess, cemented sand and silts, and some residual soils.

众所周知，由于含水量的增加，可湿性土壤的体积会显著减少，导致地基下沉，这进一步损害了建筑物并降低了其使用能力。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大部分地区都有可塌陷的土壤。随着人类活动在这些地区的不断增加，岩土工程工程师必须学会如何处理这种难处理的土壤。易塌陷的土壤包括：黄土、胶结砂和粉土以及一些残积土。
