| 中文摘要:高速公路类土质路堑边坡是边坡领域的一种重要类型,在工程特性方面与土质边坡或岩质边坡具有明显差异。深入认识该类边坡的工程特性和失稳机理，对该类边坡施工期间的安全建设以及正常运营期间安全评估具有重要意义。基于高速公路类土质路堑边坡工程地质特点、边坡变形影响因素，结合盘兴高速公路K5滑坡变形监测预警实例，提出了采用位移速度比率作为预警参考值的滑坡预警方法，并在松铜一标ZK5 410～485段左侧边坡成功预警，避免了人员伤亡，减轻了经济损失。为类土质路堑边坡工程设计、工后防治、安全运营提供指导。 |

| Abstract:Pseudo-soil cutting slope is an important type of slope in engineering construction with obvious differences between pseudo-soil slope and soil slope in terms of engineering characteristics. It is of great significance to get an in-depth understanding of engineering characteristics and instability mechanism on the pseudo-soil slope for safety construction and assessment during operation period. Based on the geological properties of highway pseudo-soil cutting slope and the influence factors of slope deformation, according to the example of K5 landslide deformation monitoring and early warning of Panxing highway, a landslide early warning method is put forward with displacement velocity ratio as early warning reference value, which made successful early warning in the left slope of ZK5 410～485 in Songtao-Tongren 1 bid section to avoid the casualties and reduce the economic loss, which provides useful guidance for engineering design, post-construction control and safety operation of pseudo-soil cutting slope. |
