岩质路堑边坡的评价方法与坡率设计

Methods for Rock Cut Slope Evaluating and Design of Ratio of Slope

辽西地区属低山丘陵地貌,公路建设中深挖路堑不可避免,形成的高边坡多为岩质边坡,边坡评价与设计成为一个重要问题。本文系统阐述了岩质边坡的基本评价方法以及边坡坡率设计的经验公式,并结合工程实例进行了具体分析。对工程实践具有指导意义。

Liaoxi Area belongs to low mountain hilly landform. Deep excavation of cut can not be avoided over there. The formed high slope is largely rock one. Thereby, the slope evaluation and design have been becoming an important problem. The paper systematically elaborates basic evaluations for rock slope and empirical formula for slope ratio design, and makes concrete analysis by way of project example, which has guiding significance to practical project.
