南疆盐渍土路基盐-冻胀变形综合防治技术研究

Integrated control technology of salt-frost heave deformation in saline soil subgrade of southern Xinjiang

盐渍土盐-冻胀变形对新疆南疆地区的道路路基造成了不同程度的破坏,尤其对南疆新建城市阿拉尔市和图木舒克市的城市道路造成了严重的变形破坏。根据南疆盐渍土工程性质及盐-冻胀变形试验研究结果,作者总结提出了"一个加强、两个严格、三个注重"的盐渍土路基盐-冻胀变形综合防治原则和"五步骤"综合防治技术与工程措施,在南疆阿拉尔市胜利大道的改建工程中得到了应用,初期防治效果较明显,其最终防治效果需通过今后三年在道路的使用期间对路面变形的监控量测结果来进行评价。

Southern Xinjiang is an inland arid desert region with wide distribution of saline soil and great saline soil disasters of projects.Since the differences in landform and groundwater distribution in different areas of southern Xinjiang,there is a clear distinction in saline soil properties,and the prevention of the disaster in saline soil exists uncertainties.In seasonal frozen soil areas of southern Xinjiang,the expansion of sulfate salts and chloride salts and their dissolved collapse cause deformation and...
