摘　　要：通过对三种固沙剂的固沙结层的力学强度与抗风蚀能力进行试验对比研究,揭示两者的内在关系,从而为制定化学固沙标准提供依据。实验表明,固沙结层的粘聚力随固沙剂用量增大而增大,并且成直线关系。固沙结层临界侵蚀风速与固沙剂用量呈线性关系,相关性很好;除了粘聚力外,材料的性质对抵抗风沙流的侵蚀也有很大的影响。Laboratory experiments were conducted to evaluate the effect of three chemical sand stabilizers crusts designed to stabilize loosen sand.This research presented the results of experiments of shear strength and the erosion properties of three crusts at laboratory scale.The results showed that cohesive strength was linear increase with the dosage of sand stabilizer and coefficient of internal friction was somewhat complex with the dosage of sand stabilizer: linear relationship with brittle materials and non l...
