摘要
以开阳高速公路改扩建项目K3266+100~K3266+270左侧高边坡为研究对象,分析了路堑高边坡失稳的原因及其在天然工况和连续降雨工况下的安全系数变化规律,并从开挖前准备、开挖方法、开挖顺序、雨季施工等方面探讨了路堑高边坡的施工要点。
Taking the left high slope ofK3266+100~K3266+270 section ofKaiyang expressway reconstruction and expansion project as the research object,this paper analyzes the reasons for the instability ofthe high cutting slope and the variation law of the safety factor under natural conditions and continuous rainfall conditions,and discusses the construction points of the high cutting slope from the aspects of preparation before excavation,excavation method,excavation sequence,rainy season construction,etc..
