为解决黄土挖方段路基外边缘保护距离不足,自然边坡较陡情况下,采用填土反压护坡方法,能增加路基外边缘安全距离,减少路中线调整产生的挖方量,防止在雨水冲刷和车辆震动下陡边坡的破坏,保障道路行车安全。文章结合工程实际,重点讨论利用填土反压护坡来防护挖方段黄土外边坡,解决保护距离不够的问题,使挖方段路基外边坡保持稳定,保障行车安全。
In order to solve the problem of lack of protection distance on the outer edge of embankment in loess excavation section and the steep slope of natural slope, the backfilling slope protection method can increase the safety distance of embankment outer edge and reduce the excavation amount of road center line adjustment, The destruction of steep slopes under the vibration of vehicles ensures the driving safety of roads. Combining with engineering practice, this paper focuses on the protection of digging loess slope by using backfill pressure of backfill, and solves the problem of insufficient protection distance so as to keep the outer slope of excavation section roadbed stable and ensure traffic safety.
