摘　　要：拱形骨架护坡是广泛应用于铁路、公路工程边坡的一种防护措施。目前其骨架结构尺寸设计基本采用经验类比法,缺乏理论依据。鉴于此,以某铁路工程为依托,在分析边坡破坏机理的基础上,通过对临界冲刷高度、边坡表层溜塌土体的下滑力计算,提出了合理的骨架结构尺寸。The arch skeleton slope protection is a protection measure widely applied to railway and highway engineering slope. At present, the experiential analogism is adopted for skeleton structure size design, which is lack of theoretic basis. of slope, the clinical Whereas, relying on railway engineering, on the basis of analyzing damage mechanism scour altitude and sliding force of slope surface collapse soil were calculated and reasonable skeleton structure size was put forward.
