摘　　要：以广东省云浮罗定至茂名信宜(粤桂界)高速公路为例,结合高速公路路基边坡的地形地貌和地质条件,分析了综合防护技术措施在高边坡中的应用要点,并对高边坡滑坡进行优化整治分析。实践得出,路基高边坡防护是高速公路建设的核心难点,不同路段地形地貌和地质水文条件差异明显,仅凭单一的防护技术,难以满足高速公路路基边坡防护要求,根据高边坡滑坡情况,修整滑塌部位,对土体进行反压,接着用C20混凝土修整坡面,再配合锚索框架梁、锚杆格梁、客土喷播等综合防护技术,实现对高边坡的成功防护,确保了高速公路路基质量,维护了生态环境,值得类似工程参考借鉴。Combined with the actual situation of Yunfu Luoding to Maoming Xinyi Expressway in Guangdong Province,based on the topography and geological conditions of the roadbed slope of the expressway,the application points of comprehensive protection technology measures in high slope were analyzed,and the landslide of high slope was optimized and analyzed.According to practice,protection of roadbed high slope is the core difficulty in expressway construction.Different sections of road have obvious differences in topography,landform and geological and hydrological conditions,and it is difficult to meet the protection requirements of highway roadbed slope only with a single protection technology.According to the landslide situation of high slope,the collapse part is repaired,the soil is reversely compressed,and the slope is repaired with C20 concrete.Combined with integrated protection technology such as anchor cable frame beam,anchor grid beam and adding-soil spraying,the successful protection of high slope is realized,the quality of highway roadbed is ensured,and the ecological environment is maintained,which is worthy of reference for similar projects.
