摘要
在已有成果的基础上采用新型高分子材料SH固化剂固化黄土,通过改良坡面黄土的工程性质,提高坡面抗冲刷性能。利用室内试验装置人工模拟边坡顶端来流冲刷,研究采用SH固化剂和固土植草相结合的方法加固黄土边坡,以边坡坡面产流产沙特征评价抗冲刷性。结果表明:SH固化黄土坡面后,坡面径流含沙量比黄土坡面显著减小,随SH掺量增加,含沙量递减,抗冲刷性明显增强; SH固化植草坡面的产流产沙性能说明化学与生态结合防护黄土边坡坡面冲刷更为有效。
Bases on the existing achievements,a curing agent of new polymer material SH is used to solidify loess. By improving the engineering properties of slope loess,the slope erosion resistance is improved. Used the indoor test device to simulate the artificial slope at top to suffer erosion,the runoff and sediment variation characteristics and anti erosion protective effect of loess slope solidified by SH with seeding are studied. The results show that the runoff and sediment of loess slope solidified by SH decreases significantly. With increasing SH dosage,the sediment concentration decreased,so erosion resistance is significantly enhanced.The runoff and sediment properties of SH solidification seeding reveal that chemical combined with ecological erosion protection on loess slope is more effective.
