摘　　要：山区公路常见的地质灾害有滑坡崩塌等,当桥址处存在滑坡时严重威胁了行车安全和结构安全。以省道岚马线罗汉沟大桥处老滑坡为例,通过现场勘查、室内试验和理论分析等,研究了该老滑坡的形成条件和稳定性,提出并采取了反压回填处置+坡面防护+排水防护综合处理措施,有效确保了滑坡稳定和桥梁结构的安全,为今后遇到类似问题的工程提供一定参考。The common geological disasters of mountain highway include landslide and collapse.When there is landslide at the bridge site,it seriously threatens the safety of driving and structure.This paper takes the old landslide at Luohangou bridge pier line of provincial highway named Lanma as an example,studies the formation conditions and stability of the old landslide through field investigation,laboratory test and theoretical analysis,and proposes and adopts comprehensive treatment measures of back pressure backfill treatment+slope protection+drainage protection,which effectively ensures the stability of landslide and the safety of bridge structure,and provides a reference for projects with similar problems in the future.
