厚层基材喷射植被护坡的抗侵蚀实验研究
Experimental Study on Erosion Stability of Thick Layer Base Material Spraying Bio-Slope-Engineering
-
摘要: 基材混合物的抗侵蚀性是评价厚层基材喷射植被护坡的重要指标之一。采用人工降雨实验,研究了不 同配比对基材混合物的侵蚀模数的影响。结果表明:种植土含量的提高或有机质和纤维的含量降低,基材混合 物的抗侵蚀性减弱;坡面植被可提高基材混合物的抗侵蚀性。研究结果对合理选择基材混合物的组成及使用比 例有重要意义。Abstract: The erosion stability of base material mixture is one of the important indices of evaluating thick layer base material spraying bio-slope-engineering. Based on artificial rainfall experiments, the effect of base material mixtures with different compositions on its erosion modulus is studied. The results show that the erosion stability of base material mixture is decreased by the increase of planting soil and the reduction of organic materials and fibers, but is increased by slope vegetation.
