摘　　要：湿陷性黄土作为复杂地基类型,土工试验分析尤为重要。通过对湿陷性黄土地区同区域间隔近二十年土体的物理力学性质及湿陷性做对比研究,结果表明两时期土体物理性质相仿,而力学性质受人为影响差异较大,新勘查时湿陷量大幅降低,重新界定了该区域湿陷性黄土层,为湿陷性黄土评价提供有效参考。Collapsible loess is a complex foundation type,and the analysis of geotechnical tests is particularly important.Through the comparative study of the physical and mechanical properties and collapsibility of the collapsible loess in the same area with an interval of nearly 20 years,the results show that the physical properties of the soil in the two periods are similar,while the mechanical properties are greatly different under the influence of man.
