山区道路高陡路堤边坡设计研究

Research on Design of High and Steep Embankment Slopes of Mountain Road

针对山区道路建设中常见的高陡路堤边坡问题,依托工程实例对高陡路堤自然放坡、挡土墙支护和放坡+挡土墙组合方案进行定性和定量比较,并选取具有代表性的圆弧形滑裂面和折线形滑裂面对边坡进行稳定性分析。研究结果认为,对高陡路堤边坡设计选取组合方案在施工和经济方面皆具有一定的优势。

Aiming at the common problem of high and steep embankment slopes in mountain road construction,relying on engineering examples,qualitatively and quantitatively compare the high-steep embankment natural grading,retaining wall support and grading+retaining wall combination scheme,and select representative Stability analysis of circular arc-shaped slip surface and broken-line slip surface.The results of the study suggest that the combination of high and steep embankment slope design options has certain advantages in construction and economy.
