摘　　要：针对厚层砂土型河道岸坡坡面稳定问题,采用PPS型固化剂对岸坡表层砂土进行加固。采用模拟冲刷试验对改良表层砂土的抗冲刷性能进行了一系列试验研究,并结合扫描电镜对改良后砂土的内部微观结构进行了较为深入分析。研究成果为高分子固化剂在河道岸坡厚层砂土坡面生态防护应用中的作用提供了一定的参考依据。Focusing on the slope stability problem of bank slope with thick sandy soil layer,the PPS soil stabilizer was introduced in the present study to modify the topsoil meeting the engineering requirements. A series of simulated erosion tests were performed to evaluate the erosion resistance of the treated soils. SEM images were also used to further understand the inter-particle interactions. The results obtained from the experimental tests can provide some useful knowledge for the actual applications of macromolecular curing agent in the ecological protection of sandy slope.
