针对目前黄土地区公路边坡防护中存在的问题 ,提出了采取土工格室内植草的方法对黄土地区公路边坡进行防护。通过对土工格室生态护坡作用机理和抗滑稳定性的理论分析 ,给出了平铺式和叠砌式生态护坡的结构型式、适用条件、设计计算方法及施工工艺 ,确定了相关参数的取值范围。工程实践表明 ,与常用的护坡方法相比 ,土工格室生态护坡不但具有更高的抗冲蚀能力 ,而且可节省工程造价 2 0 %～ 4 0 % ,同时能快速恢复生态环境 ,绿化边坡、美化公路沿线景观 ,是一种较好的黄土地区公路边坡防护形式
Aiming at the problems existing in slope protection of highway in loess area, the paper puts forward the method of using geocell indoors to protect the highway slope in loess area. Through the theoretical analysis of the mechanism and stability of ecological slope protection in geocell, the structure type, applicable conditions, design and calculation methods and construction technology of tiled and stacked ecological slope protection are given, and the relevant parameters are determined Value range. Engineering practice shows that, compared with the commonly used methods of slope protection, the geocell ecological slope protection not only has higher erosion resistance, but also saves 20% ~ 40% of the project cost, and at the same time can quickly restore the ecological environment and green slope , Beautify the landscape along the highway, is a better loess area highway slope protection form
