Environment-friendly loess roadbed improvement method considering freeze-thaw effect and dynamic stability
The invention discloses an environment-friendly loess roadbed improvement method considering a freeze-thaw effect and dynamic stability. The method comprises the steps that the maximum dry density and the optimal water content of loess are measured according to an indoor compaction test; the lignin fibers are poured into loess according to the mass ratio to be mixed, and water is not added in the mixing process; after the lignin fibers and the loess are evenly mixed in a dry mode, water is added into the dry mixed soil, the mixture is continuously stirred to be even, and the water content of the wet mixed soil is the measured optimal water content of the loess; according to the method, pollution-free environment-friendly materials are used for improving the performance of the loess subgrade, the strength of the loess subgrade under the freezing and thawing cycle condition can be enhanced, strength damage to the loess subgrade in the freezing and thawing cycle action process is reduced, and the quality of the loess subgrade is improved. The stability of dynamic deformation of the loess roadbed in the freezing and thawing cycle action process is improved, the improvement cost is effectively reduced, and the negative influence of engineering construction on the ecological environment is relieved.
本发明公开了一种考虑冻融效应和动态稳定性的环保黄土路基改良方法，其包括按照室内击实试验测定黄土的最大干密度和最优含水量；将木质素纤维按照质量配比倒入黄土中进行拌和，拌和过程中不加水；待木质素纤维和黄土干拌混合均匀后，向干混合土中加水继续搅拌至均匀，湿混合土的含水量为测定的黄土的最优含水量；以黄土的最大干密度和路基的控制压实度，确定改良黄土压实密度，回填压实改良黄土路基，本发明使用无污染的环保材料改良黄土路基性能，能够增强冻融循环条件下黄土路基强度，减小冻融循环作用过程中黄土路基的强度损伤，提高冻融循环作用过程中黄土路基动态变形的稳定性，有效降低改良成本，减轻工程建设对生态环境的负面影响。
