摘要
高速公路的边坡防护治理一直以来都是工程建设的重要内容,植被生态护坡方式的应用和实践既实现了边坡防护又有效保护了环境。但植被根系和土体相互作用的力学特性比较复杂,同时其护坡的效果及其稳定性有待深入研究。从植被护坡的基本理论及分析方法入手,对青海地区某公路边坡项目建设中植被护坡的稳定性进行了分析,希望能够为类似工程边坡的安全和稳定提供参考。
The highway slope protection has always been an important part of engineering construction practice. Traditional slope protection methods such as retaining wall, anchoring and shotcrete have induced many negative impacts on the ecological environment. The application of vegetation ecological slope protection not only achieves slope protection but also effectively protects the environment. With the harmonious development of the ecological environment and the human civilization, the application of the vegetation slope protection technology in the highway slope protection engineering will be more and more popular. However, the mechanical properties of vegetation roots and soil interactions are complex. The effect and stability of the slope protection needs further study. Therefore, this paper starts with the basic theories and analysis methods of the vegetation slope protection. The stability of the vegetation slope protection in the construction of highway slope project in Qinghai is analyzed with an aim pf providing reference for the safety and stability of similar engineering slopes.
