| 摘 要： | 常吉高速公路湘西段地形起伏大, 地质条件复杂, 路堑边坡数量众多, 边坡稳定性问题突出。本文根据岩体产状与边坡坡面的关系研究, 认为常吉高速湘西段路堑边坡主要包括顺向坡、正交坡与反向坡, 其中顺向坡的变形破坏机制与它的物质组成、岩体结构合风化程度等有关。分析、总结了路堑边坡的变形破坏模式, 提出并实施了针对不同边坡结构类型与变形破坏模式的边坡防护措施。

| Abstract: | Many cut slopes were formed on western section of the Changde-Jishou Expressway in Hunan province,where the topographical and geological conditions are complex.Stability issues of the cut slopes are outstanding.Based on a detailed geological survey,this paper presents the structure classification of the cut slopes according to the relationship between rock mass occurrence and slope dip direction.The relationship between deformation and failure mechanism and its composition,rock structure and weathering extent is studied in detail.The paper further identifies the deformation and failure modes of the cut slopes.It suggests the safety measures corresponding to different slope types and failure modes.The suggestions were utilized and achieved excellent results. |
