摘要:: 基于四个纤维丝植生层厚度、三个典型坡度下的模拟降雨试验,探讨了特大暴雨和径流冲刷条件下纤维丝固土护坡固土植生法在模拟边坡上的水土保持效应及纤维丝的减流减沙机理,并确定了各个坡度下适宜的喷丝植生层厚度。结果表明:纤维丝固土护坡固土植生法在早期无植被覆盖下经受强降雨时能够有效的防治植生层流失,纤维丝是通过有效减小雨滴溅蚀和消减径流动能,及内部加筋补强作用共同提高植生层抗冲性;坡度30°条件下能抗当地最大降雨强度冲刷时的纤维丝植生层厚度应保持在3 cm以上;坡度45°条件下,纤维丝植生层的适宜厚度应保持在6 cm左右;对于60°边坡,其适宜的喷丝植生层厚度应保持在6 cm以上。

Abstract:: Soil and water conservation effect and the filaments runoff and sediment reduction mechanism of continuous spraying filaments and fixing soil planting technology on simulated slopes under heavy rainfall and flow scouring was studied based on simulation experiments with four planting layer thickness and three gradients. And the appropriate planting layer thickness in each gradient was proposed. The results showed that spraying filaments planting subjected to heavy rainfall can effectively combat the loss of vegetation layer in the early lack of vegetation cover, filaments through effectively reduce raindrop splash and abatement runoff kinetic energy, and reinforced reinforcement effect together to improve the erosion resistance of vegetation. The appropriate spraying planting layer thickness which could be resistant to the local maximum rainfall intensity under the condition of the 30° side slope should be maintained at more than 3 cm; and about 6cm was the appropriate thickness for the 45°; for 60°slope, the suitable thickness of the planting layer should be maintained at more than 6 cm.
