【摘要】 边坡是各种河道及水利枢纽组成部分之一,作者从边坡侵蚀基本理论出发,分析植物根系固土基本原理, 建立河道边坡植物固土力学模型,并针对典型河道边坡侵蚀形式提出几种河道边坡植物固土方案。实验证明植物根系通过与土体的缠绕等作用稳定土体结构,增强河道边坡土壤的抗冲性能、增大了边坡的安全系数,从而提高河道边坡抗侵蚀的能力,同时又能将工程造价降低到传统边坡防护工程造价的1／5。更多还原

【Abstract】 By the principle of slope erosion, authors analyse the basic principle of plant root reinforcement function to soil, set up the mechanics model of the use of rooting soil of the riverway slope, and put forward several methods on it in this paper, which aim at typical erosion way of the riverway slope.The experiment results show that the plant root system can obviously enhance the shearing strength of the slope soil, stabilize the soil structure by wrapping it, strengthen the anti-eroding performance of it, increase the safty factor of the slope, and thereby advance the anti-erosion capability of it, reduse the project cost by 20% compared with the traditional way. The etablishment of the mechanics model of the riverway plant stabilizing the slope soil offer an important therotical basis in terms of analying the mutual relationship between the plant root system and the soil.更多还原
