高速公路红砂岩高路堑边坡加固处治技术研究

针对湘西高速公路建设中出现的大量红砂岩高路堑边坡失稳破坏现象,探讨了软硬互层红砂岩高路堑边坡的破坏机理、稳定性分析方法,提出了防水、防风化、坡体预应力中空锚杆注浆、平式排水管引排坡体裂隙水的边坡防护加固措施,实际应用表明,该处治措施行之有效,尤其对湘西红砂岩地区的高速公路高路堑边坡防护加固具有指导意义。

Study on Treatment of High-cut Red Sandy Rock Slope in Expressway

Aiming at a lot of landslide of the high-cut red sandy rock slope occurred on expressway in west of Hunan Province,the mechanization of which has been studied,so as to a stability analysis of sliding.at the same time,A effective measure with water seal,efflorescence prevention,prestressed hollow-core grouted anchor in slope and weep pipe to drain crevice water has been suggested.The application indicates the method is very effective.Especially it has directive function to cut slope protection at the high-cu...
