通过对不同分子量和电荷密度的聚丙烯酰胺(PAM)组合研究,说明所有的PAM处理均能改善土壤的渗透率,其中以中等分子量和电荷密度的处理效果为最优。该结论可望为生态护坡工程应用PAM提供试验依据和理论支持。
Through the combination of polyacrylamide (PAM) with different molecular weights and charge densities, it shows that all PAM treatments can improve soil permeability, of which the treatment effect of medium molecular weight and charge density is the best. This conclusion is expected to provide experimental basis and theoretical support for the application of PAM in ecological slope protection project.
