摘要
土壤胀缩是土壤在干燥、湿润交替变化过程中所表现出的土壤容积随含水量改变的关系。就土壤容积变化的表示方法、土壤干裂特征、变性土土壤水运动机理,土壤的收缩特征曲线和影响土壤收缩的相关因素五个方面进行了总结和回顾,同时,就以后的研究工作提出了展望。
Soil swelling-shrinkage is related to change in soil volume with water content in the process of soil drying and wetting. The review is summarized in some aspects ,such as expression methods of soil volume change, characteristic of soil crack,water move mechanics in expansive soil ,models of soil shrinkage characteristics curve and related factors affecting soil swelling-shrinkage. Meanwhile,prospect is noted for future research work.
