山区公路边坡滑塌成因分析及治理方案研究

Analysis of Causes of Slope Collapse on Mountainous Highways and Research on Treatment Plans

文中研究了某公路边坡滑塌的具体成因,并结合滑坡治理原则合理选择治理方法。综合考虑现场条件、施工难度及经济效益等因素,采用“挡墙+坡面挂网喷射混凝土”联合治理措施,卸载滑坡带上缘土方、完善边坡排水系统、边坡防护挂网喷射混凝土并种植爬墙虎、增设仰斜式挡土墙稳固坡脚。现场治理效果表明该治理方案合理可靠,可为类似工程提供借鉴。

This article studies the specific causes of slope collapse on a certain highway,and selects a reasonable treatment method based on landslide control principles.After comprehensive consideration of site conditions,construction difficulty,and economic benefits,a joint treatment measure of "retaining wall+slope surface hanging net sprayed concrete" is adopted.The measures include unloading the upper edge soil of the landslide zone,improving the slope drainage system,hanging net sprayed concrete for slope protection and planting ivy,and adding inclined retaining walls to stabilize the slope foot.The on-site governance effect shows that the governance plan is reasonable and reliable,and can provide reference for similar projects.
