Plateau cold and arid region strong alkali salinized soil roadbed construction method
The invention discloses a construction method of a strong alkali saline soil roadbed in a plateau cold and arid area, which comprises the following construction quality measures: roadbed filler selection, original ground treatment, geomembrane (cloth) separation layer arrangement, water content control, compactness control, structure corrosion prevention, special roadbed treatment and the like. The utilization rate of excavated earthwork is increased, ecological and environment-friendly damage is reduced, the construction quality is improved, the cost-reducing and efficiency-increasing effects are remarkable, the occurrence probability of related diseases is greatly reduced, and the investment cost of later maintenance is effectively reduced. According to the method, the diseases such as salt expansion, melt sinking, frost boiling, corrosion and secondary salinization caused by the strong-alkali salinized soil in the plateau cold and arid region to roadbed engineering are effectively solved, a more advanced construction method is provided for construction of similar engineering, and the popularization and application prospects are wide.
本发明公开了一种高原寒旱区强碱盐渍土路基施工方法，通过路基填料的选择、原地面处理、设置土工膜(布)隔断层、含水量控制、压实度控制、构造物防腐和特殊路基处理等施工质量措施，加强挖土方利用率、减少生态环保破坏、提高施工质量、降本增效效果显著，大大降低相关病害发生的几率，有效降低了后期养护投资费用。本发明有效解决高原寒旱区强碱盐渍土对路基工程造成的盐胀、溶陷、翻浆、腐蚀和次生盐渍化等病害，为同类工程施工提供了更为先进的施工工法，推广应用前景广阔。
