摘要
山区公路的建设可能造成边坡损坏隐患,需要及时予以防护和整治。分析总结了边坡破坏类型、原因、主要处理原则及常用边坡防护形式和具体措施。皂市水库库区公路某边坡在水库蓄水后,安全系数不足,存在边坡崩滑体整体失稳的可能性,经过对各种治理方案的优缺点比较,决定采用"削方减载+坡面锚固护坡+地表截排水"的治理方案。该边坡经过处理后,安全系数得到提高,保证了皂市水库蓄水后公路运行的安全。
The construction of road in mountain area would lead to potential danger of slope destruction, so the slope should be protected and treated. The slope destruction type, causes, major treatment principle and common slope protection forms and measures are summarized and analyzed. Taking the surrounding road of Zaosbi Reservoir as example, the slope safety coefficient was small and the collapse body of the slope might be instable as a whole. By comparison of advantages and disadvantages of various treatment schemes, the combination of excavation for reducing load, slope surface anchoring and surface flow cutoff was adopted. After treatment, the safety coefficient was improved and the operation safety of the road was guaranteed.
