中文摘要	利用粉煤灰与聚丙烯酰胺(PAM)的物化性质,构造与土壤性质相似的沙土固结层,通过风洞试验模拟沙土风蚀过程,研究沙土固结层对沙土风蚀的抑制作用.试验对照组为沙土,试验组为按质量比将粉煤灰(10%、20%)和PAM(0.05%、0.1%)分别与沙土交叉配比混合(T1、 T2、T3、T4).研究结果表明:粉煤灰、PAM和沙土形成的沙土固结层可以有效提高沙土的起动风速,控制单一变量条件下,增加PAM添加量可以提高沙土固结层起动风速、增加粉煤灰添加量会导致沙土固结层起动风速降低;增加粉煤灰和PAM添加量可以降低沙土风蚀量;粉煤灰(10%)和PAM(0.1%)形成的固结层效果最好.
英文摘要	The consolidated soil layer (CSL) was composed of fly ash (FA) and polyacrylamide (PAM), and its property was similar to soil. The resistance to wind erosion of CSLs was studied using an indoor wind tunnel under simulated wind erosion conditions. The CSL was a mixture of FA (10% and 20%), PAM (0.05% and 0.1%) and the experimental soil (classified as a sandy soil), named as T1, T2, T3, and T4. The results showed that the threshold wind speed of the sandy soil was significantly increased due to the formation of CSL by FA and PAM, exhibiting an increasing trend with increasing addition rate of FA and PAM. The wind erosion amounts of different CSLs were all decreased when compared with that of the sandy soil. The resistance to wind erosion of the CSL consisting of 10% FA and 0.1% PAM was strongest.
