| 摘 要： | 实验资料表明，0.02-0.08mm之间的架空孔隙是引起极强湿陷和强湿陷的主要原因；0.008-0.02mm之间的支架孔隙是引起中等湿陷和弱湿陷的主要原因；不同湿陷性的黄土孔隙组合不同，极强湿陷和强湿陷黄土的突出特点是架空孔隙组合成网格状；湿陷后减少的孔隙数量在0.8-20%之间；宏观孔隙对湿陷也有一定影响；黄土的湿陷性是在干旱与半干旱地区的土壤化过程中产生的。

| Abstract: | Experimental data shows that the pores 0.02 and 0.08mm in diameter built on stilts are the main factor causing extreme intense and intense collapsibility, support pores 0.008 and 0.02mm in diameter are main factor carusing moderate and weak collapsibility.The different combinaction of pores results in different grades of loess collapse,the con spicuous characteristics of loess of extreme intense and intense collasibility are that the pores built on stilts occur in the form of meshes.The reduced amount of pores after collape is between 0.8-20%.Macropores also behave collapsibility to a certain extent,the collasibility of loess was formed in the porcess of soil forming in arid and semiaridareas. |
