摘要
针对六寨 水任二级公路存在的炭质泥岩边坡稳定性问题 ,研究炭质泥岩边坡工程地质特性、变形破坏模式、稳定性影响因素等 ,分析评价其稳定性 ,将沿线的边坡分为四类 ,有针对性地提出防治措施 ,既增强边坡稳定性 ,又改善线路景观效果。本着一次根治 ,不留隐患 ,综合处理 ,经济合理 ,施工方便的原则 ,采取了喷锚网、挂网喷浆、预应力锚固、土工材料绿化和客土喷播等五种防护技术措施 ,沿线区治理边坡 75个 ,总面积 3 5万m2 ,取得了较好的成果。
As to the problems in the stability of the carbon mudstone slopes existed on the 2 nd class highway (Liuzhai Shuiren), a study has been performed on the geological features of the carbon mudstone slope engineering, the model of deformation damage and the factors affecting stability, etc. Through the analysis of the stability, the slopes alongside are divided into 4 categories with respective preventative measures not only strengthening the slope stability, but also improving the landscape effect alongside. Based on the principles of once permanent control with no hidden troubles as well as comprehensive treatment with reasonable cost and convenient construction, five technical measures for protection have been adopted including shortcrete and rock bolt, net grout injecting, prestressing anchorage, geotextiles aforestation and foreign soils spraying sowing. With these approaches, 75 slopes alongside totaling 350,000m 2 have been improved with good results.
