盐渍土顾名思义就是含盐量有了一定数量的土,盐渍土主要分布在我国的西北部干旱地区的盆地与平原当中,例如青海,甘肃,宁夏,内蒙古等地区。由于盐渍土的腐蚀性能特别大,用在公路建筑上容易使地基变得松软,不稳定。因此,对工程地基来说是有一定的危害程度的。因此,在西北一些地区,盐渍土地区的公路设计和其他地区的公路设计要求不太一样,更加有着具体的技术和设计要求。 Saline soil, as its name implies, contains a certain amount of soil with salt content. Saline soil is mainly distributed in basins and plains in the arid areas of northwestern China, such as Qinghai, Gansu, Ningxia and Inner Mongolia. Due to the special corrosion of saline soil, it is easy to make the foundation soft and unstable when used in highway construction. Therefore, the engineering foundation is a certain degree of harm. Therefore, in some areas of Northwest China, the design of roads in the saline soil area is not the same as that of other areas and more specific technical and design requirements.
