根据陕北地区某一大厚度湿陷性黄土场地勘察资料，对比了现场浸水试验与室内土工试验两种条件下的自重湿陷量，结果表明，现场实测值远小于室内试验计算值，尤其场地的自重湿陷特性与传统的认识差别较大。经调查研究所在区域其他相关试验资料，也出现类似的情况。该文从试验条件、黄土成因、地质时代等多方面对陕北大厚度黄土地区的湿陷性进行了分析和总结，并提出了建议。

According to the survey data of big thickness collapsible loess site in northern Shanxi area , the self-weight collapse settlement is compared between field immersion test and laboratory soil test .The results indicate that the measured values of field test are far less than the calculated values of indoor test , especially the collapsible characteristics have a bigger difference than traditional understanding .After de-tailed investigation on other relevant test data in the area , we found that the similar problems are also ap-peared.The paper analyzes and summarizes the collapsible of big thickness loess in northern Shanxi area from the test conditions, loess formation,geological age etc., and some suggestions are also put forward .
