引言我国西北部很多地区分布着大面积的盐渍土地,大者如柴达木盆地、准噶尔盆地、塔里木盆地,小者如焉耆盆地、库木库里盆地、茶卡盐池等。道路通过这些地区,由于区域工程地质条件的不同,得到了极为不同的结果:有的盐渍土地区,地面和路基常发生松软翻浆阻碍行车的现象,如新疆焉耆、甘肃张掖等地的道路翻浆;有的盐渍土地区对道路却表现了优良的品质,如青海柴达木盆地的敦噶路南段、中干线及
Introduction Large areas of salinized land are distributed in many parts of northwestern China, such as the Qaidam Basin, the Junggar Basin and the Tarim Basin, and the smaller ones such as the Yanqi Basin, the Kurokul Basin and the Chakayanchi. Roads passing through these areas have very different results due to the different geological conditions in the area. In some saline soil areas, the phenomenon that soft soil adheres to the ground and the subgrade often impedes traffic, such as road dumping in Yanqi in Xinjiang and Zhangye in Gansu, Some salty soil areas showed excellent quality on roads, such as the south section of Dun Kar Road in the Qaidam Basin of Qinghai Province, the middle trunk line and
