摘要
针对红粘土边坡病害现象,采用现场调查、观测与统计的方法,对江西省10条高速公路,6条国道公路总共294处边坡的破坏形式、特点和边坡防护类型、坡高、坡率,稳定性等方面进行调查分析。调查结果发现,无支护结构下红粘土边坡病害存在坡面冲蚀、剥落、冲刷、溜方、坍塌等现象,以浅、表层破坏为主,整体破坏相对少见;支护结构下边坡破坏主要发生在植物防护处产生的小面积冲蚀、剥落等现象,边坡基本上不会出现整体滑塌,同时给出了边坡在各种支护形式下的适用坡率,为红粘土边坡的防护提供了参考。
In order to study the phenomenon of red clay slope damages,methods such as site investigation,observation and statistics were carried out to investigate the damage form,damage characteristics,slope protection types,slope height,slope rate and stability on 10 high ways,6 national highways in Jiangxi province,with a total of 294 slope areas.After the investigation and analyzing,it was found that there were erosion,spalling,washout,slipping,collapse and other kind of damages at those unprotected red clay slopes.Those damages mainly happened at the shallow or the surface of the slopes,and the overall damage was relatively less.While for those protected slope,damages such as erosion or spalling could only be seen at small plant protection areas,and the slope remained stable without overall collapse.Meanwhile,different applicable slope rates under various protection forms were put forward,which could provide reference for the protection of the red clay slope.
