在盐渍土地区,路面早期损坏十分严重。盐渍土地区的路面早期损坏与土体中盐分导致路基的盐胀、溶蚀和翻浆等病害密切相关。研究公路使用过程中盐分的迁移规律和阻盐技术对于盐渍土地区公路养护维修有重大的意义。文章通过对盐分入侵路基途径的分析,提出相应的隔断措施,并修筑试验路进行效果检验,实际效果十分明显。 In saline soil areas, pavement damage is very serious early. Early damage of pavement in salty soil area is closely related to diseases such as salt expansion, erosion and soaking caused by salt in soil. Studying the law of salt migration and the technology of salt resistance during the course of highway use are of great significance to the maintenance and repair of highway in saline soil area. Based on the analysis of the way of saline intrusion on the embankment, the paper puts forward the corresponding partition measures, and builds the test road to test the effect, the actual effect is very obvious.
