| 摘 要： | 瑞金至寻乌高速公路位于赣南地区,开挖形成的路堑边坡以砂岩、泥岩、粉砂岩为主,其强度低、易风化,且遇水软化、崩解,水稳定性差。在对沿线工程地质条件分析的基础上,提出了顺层岩质路堑边坡的破坏模式,为避免开挖过程中边坡出现顺层滑动,宜边开挖边加固。水是诱发顺层边坡失稳的主导因素,设计中应加强防排水措施。

| Abstract: | Ruijin to Xunwu highway located in south of Jiangxi,the cutting slope of excavation is mainly made of sandstone,mudstone,siltstone which is lack of strength,easy to weathering,and water softening,disintegration,poor water stability.Based on analysis of engineering geological conditions,failure modes with respect to bedding rock slope are presented.Slope reinforcement and excavation simultaneously should be adopted to avoid slope failure for this kind of bedding rock slope.Water is the dominant factor to ind... |
