岩质路堑高边坡稳定性分析及设计方法

Stability Analysis and Design Method of Rock Cutting Slope

由于周边用地和道路线形的限制,高等级公路的建设不可避免地需要穿越山区等地形复杂的地段,深路堑边坡的稳定性问题日益突出。该文以宁波大榭对外第二通道岩质路堑高边坡的设计为实例,介绍了岩质路堑高边坡的稳定性分析及设计方法,并就其施工过程及工后高边坡的防护、加固技术进行了分析。

Limited by the surrounding land and road alignment, the construction of high-grade highway is unavoidably required to pass through the mountain complex terrain. Therefore, the stability problems of deep cutting slope have become increasingly prominent. The article introduces the stability analysis and design method of rock cutting slope by the design example of the rock cutting slope of Ningbo Daxie External Passageway No.2,and analyzes its construction process and the protection and reinforcing technologies of high slope after construction.
