摘　　要：通过对黄土的5项物理力学指标与黄土湿陷起始压力进行统计分析,结果表明,天然密度与黄土湿陷起始压力中度相关,含水率、孔隙比及液限低度相关,塑限不相关;湿陷起始压力为多因素综合作用的结果,对各物理力学参数的综合统计可在确定黄土湿陷起始压力过程中提供一定参考。Based on the statistical analysis for 5 physical and mechanical index and the collapsible pressure of loess, the results show that the collapsible pressure is moderately related to the density, which is low -alcohol related to the mois- ture content and porosity, and which is not related to plastic limit. The comprehensive statistics of physical and mechanical parameter can be used to determine the initial subsidence pressure.
