摘要
为了生态加固及防护土质边坡,提高边坡抵抗较深层滑动的能力,研发了根系-拉索-石笼网共同作用的生态护坡系统。工作机理为:浅层滑坡体推动柔性石笼网挡墙前倾,乔灌木根系的抗拔力通过拉索约束住挡墙的位移,从而使坡脚土体由受剪为主改为受压为主。通过数值分析,探讨了将边坡的乔灌木根系的抗拔与石笼网柔性挡墙的变形自适应相结合,联合作用加固挡墙基底以上坡土的可行性。分析结果表明:通过镀锌过塑拉索与根系的联合作用可以有效地限制和减少土坡和柔性石笼网挡墙的渐进变形,从而维持土坡的稳定。
In order to improve the stability of slope,root-cable-gabion net flexible system was developed to control progressive deformation of slope.Mechanical and finite element analyses were performed on the root-cable-gabion net system adaptively stabilized slope.The results showed that due to the flexibility of gabion net retaining wall,root-cable-gabion net system can effectively limit and reduce the progressive deformation of slope and maintain the slope stable.
