公路工程软岩高边坡破坏和加固技术研究

Study on Failure and Reinforcement Technology of Soft Rock High Slope in Highway Engineering

为探究某公路旁软岩边坡的崩塌情况并给出治理方案,文中对公路沿线边坡进行了现场调查,结果表明,研究区采用的破坏率最高的护坡方式主要有植被护坡(82.0%),最常见的软弱岩层中,泥岩边坡的破坏率最高,最常见的破坏模式是地表侵蚀和浅层滑坡,影响边坡破坏的因素包括雨水径流排水,边坡表面不同的岩石类型、植被、边坡角度和高度。针对泥岩边坡破坏特点,文中还提出了土壤-轮胎-植被加固方法,并验证了该方法的可行性。

In order to explore the collapse of the soft rock slope beside a highway,the treatment scheme is given.This paper makes an on-thespot investigation of the slope along the highway,and the results show that the most efficient slope protection method adopted in the study area is vegetation slope protection(82.0%),and the failure rate of mudstone slope is the highest in the most common weak rock formation.the most common failure modes are surface erosion and shallow landslides.The factors affecting slope failure include insufficient drainage of Rain Water runoff,different rock types and vegetation on the slope surface,slope angle and height.According to the failure characteristics of mudstone slope,the soil-tire-vegetation reinforcement method is put forward,and the feasibility of the method is verified.
