【摘要】：阿拉尔市道路受盐胀_冻胀变形较严重,通过对市内10条沥青混凝土道路路面破损情况进行调查和评估,结合市区土质、水文、气候及路面结构条件,分析道路结构盐胀_冻胀变形原因,针对盐分、水分影响,提出路基填料去盐处理和道路结构排水、防水措施.结果表明:改建道路中采用级配碎石基层、设置高挡水墙和基底隔断层等措施取得了较好的排水、防水效果,可为后期市区道路改建提供参考.
[Abstract]:The road in Alar is seriously deformed by salt heaving and frost heaving. Through the investigation and evaluation of the pavement damage of 10 asphalt concrete roads in the city, combined with the soil quality, hydrology, climate and pavement structure conditions in the urban area,This paper analyzes the causes of salt heaving and frost heaving deformation of road structure. Aiming at the influence of salt content and moisture content, the measures of desalting subgrade packing, drainage of road structure and waterproofing are put forward.The results show that measures such as graded crushed stone base course, high water retaining wall and basement fault are adopted in the reconstruction of road, and good drainage and waterproof effect are obtained, which can be used as reference for road reconstruction in the later stage of urban area.
