大坡度拱形防护工程施工技术研究

Analysis on construction technology of large slope arch protection engineering

公路开挖造成的边坡稳定性问题已成为路基施工不可忽略的环节,公路建设不断呈现偏远化、基础环境复杂化趋势,为避免造成不必要的经济损失,在工程施工期间,应选择适当的防护施工技术以确保路基的使用寿命。路基边坡防护是保证路基强度和稳定性的重要措施之一,与主体工程施工相对独立,又密不可分,互相影响。分析施工工法特点,对大坡度拱形防护工程施工方法与深挖路堑开挖、高填路堤填筑技术进行探讨,通过分析施工流程及注意事项,提出了合理的施工工艺。

bThe problem of slope stability caused by highway excavation has become a non-negligible link in the construction of roadbed. The road construction constantly presents the trend of remoteness and complexity of basic environment. In order to avoid unnecessary economic losses,during the construction period,the road should be selected. Roadside slope protection is one of the important measures to ensure the strength and stability of the roadbed.It is relatively independent of the construction of the main project,and is inseparable and influencing each other. It analyzes the characteristics of construction methods,and discusses the construction methods of large gradient arch protection works,excavation of excavation roads,and filling of high-filled embankments. Through the analysis of construction processes and precautions,reasonable construction techniques are proposed.
