| 摘 要： | 本文依据西宁地区黄土的大量实际资料,对影响黄土湿陷性的两个主要因素(黄土的天然孔隙比、含水量)与黄土湿陷系数的关系进行了综合分析与归纳,论述了这两个因素对湿陷性的影响;并在数理统计基础上,提出了黄土湿陷性的判别式。对西宁黄土区的工程地质评价,具有参考与实用价值。

| Abstract: | Based on a lot of factual data of loess of Xining,the relationship between the twomain factors (naturee porosity and water content or loess)and number of Collapsibility of loesshave analysed syntheritically and the influence of these factors to collapsibility was decribed.Through mathematical statistics,furthermore, a discriminant of loess collapsibility has been putfoward. Its conclutions, therefore,have practical value as well sa referencial value for the evalua-tion of engeneering geology in the Xining loess areas. |
