摘　　要：文中以虾坝河河道边坡治理工程为例,通过建立裸坡、植被防护边坡以及三维土工网垫+植物边坡模型,测试边坡土体强度和泥沙冲刷量,分析三维土工网垫+植物边坡防护措施的具体应用效果。结果表明,单一狗牙根护坡和三维土工网垫+狗牙根边坡土体黏聚力均高于裸坡土体,且随着边坡土体深度的增加,三维土工网垫+狗牙根边坡土体黏聚力降低幅度最小,表明三维土工网垫+狗牙根护坡措施在保持土体稳定性方面的优越性;单一狗牙根护坡和三维土工网垫+狗牙根主要通过提高土体黏聚力来增强土体抗剪强度;在相同降雨条件下,单一狗牙根护坡和三维土工网垫+狗牙根护坡均能有效减少边坡泥沙冲刷量,且后者减沙效果更加明显。In this paper,taking the river slope treatment project of Xiba River as an example,the soil strength and sediment erosion of the slope are tested by establishing the model of bare slope,vegetation protection slope and three-dimensional geonet mat+plant slope,and the specific application effect of three-dimensional geonet mat+plant slope protection measures is analyzed.The results show that the soil cohesion of single dogtooth root slope protection and three-dimensional geonet mat+dogtooth root slope is higher than that of bare slope soil,and with the increase of soil depth of slope,the soil cohesion of three-dimensional geonet mat+dogtooth root slope decreases the least,indicating the superiority of three-dimensional geonet mat+dogtooth root slope protection measures in maintaining soil stability.Single dogtooth root slope protection and three-dimensional geonet mat+dogtooth root mainly enhance the shear strength of the soil by improving the cohesion of the soil.Under the same rainfall conditions,a single dogtooth root slope protection and three-dimensional geonet mat+dogtooth root slope protection can effectively reduce the amount of sediment erosion on the slope,and the sand reduction effect of the latter is more obvious.
