摘要
在盐渍土道路工程运行过程中,盐渍土内所含有的丰富的盐类、碱类成分,会对道路工程路基路面造成严重的危害,最终出现无法恢复的路基路面病害问题,对道路工程行车安全造成了较大的威胁。因此,本文以某盐渍土路基路面工程为入手点,根据盐渍土路基路面特殊性。从盐渍土路基路面翻浆病害、盐渍土路基路面坑槽、盐渍土路基路面腐蚀、盐渍土路基路面盐胀等方面,分析了盐渍土对道路工程路基路面的危害。并从路基土体更换、路基高度提升、土体浸水预溶及集料铺筑、路基强行加固夯实等方面,提出了几点盐渍土路基路面解决措施,以期为盐渍土路基路面安全稳定运行提供一定参考。
During the operation of road engineering in saline soil,saline soil contains abundant salts and alkalis,which will cause serious harm to the roadbed and pavement of road engineering,and eventually lead to unrecoverable roadbed and pavement diseases,which pose a great threat to the safety of road engineering.Therefore,starting from a saline soil roadbed and pavement project,according to the particularity of saline soil roadbed and pavement,this paper analyses the harm of saline soil to roadbed and pavement in saline soil roadbed and pavement from the aspects of slurry disease of saline soil roadbed and pavement,saline soil roadbed and pavement corrosion,saline soil roadbed and pavement swelling,etc.From the aspects of replacement of subgrade soil,elevation of subgrade height,pre-solution of soil immersion and forced compaction of subgrade,this paper puts forward some measures to solve the problems of saline soil subgrade and pavement,with a view to providing some reference for the safe and stable operation of saline soil subgrade and pavement.
