【摘要】 随着我国公路建设的高速发展，公路岩质边坡的稳定性分析及坡面防护技术的研究已成为高等级公路面临的关键技术之一。我国高等级公路建设起步较晚，建设资金有限，因此，在岩质边坡防护方面，无论从观念上、技术上和建设规模上与先进发达国家都有一定的差距。而这些差距给高等级公路建设和国家发展的长远利益带来各种程度的负面影响。本文结合郴州高等级公路建设有限公司与湖南大学合作项目“高等级公路路堑边坡实用防护方法研究”，以桂嘉新建二级公路工程为依托，对岩质边坡的稳定型分析及其防护措施进行了较系统和深入的探讨。 通过对国内外已有公路岩质边坡修筑资料的综合分析，总结了目前公路边坡设计与施工中存在的一些问题，如设计安全性差、防护措施落后、对生态保护重视不够等；介绍了国内外研究现状与发展趋势，比较了传统防护与生态防护两种方法的优缺点。针对岩质边坡的特点，对岩质边坡的失稳形式和破坏机制进行了探讨，并对影响不同岩质边坡稳定性的主要因素进行了较深入的分析，探讨了岩质边坡两种常用的稳定性分析方法：工程地质法和理论分析—力学计算法，本论文着重用理论分析法—极限平衡法分析计算边坡稳定性，并用最优化方法搜索最危险滑动面。通过用Fortran语言编程计算算例—桂嘉二级公路K32+800处边坡稳定性，并与Sweden法和Bishop法计算结果相比。结合桂嘉二级公路的实际情况，对其岩质边坡进行坡面防护和施工工艺进行优化设计，并对滑塌边坡进行稳定性分析和治理。 通过对国内外边坡防护方法的综合分析，提出了适合高等级公路的坡面防护思路与方法；在国内外边坡生态防护研究的基础上，较全面地分析了边坡生态防护的工作机理，为进一步研究打下良好的基础。此外，本文结合理论分析与工程实践，成功地完成了桂嘉二级公路岩质边坡的坡面防护实践，通过周密系统的施工方案与现场检测，取得了丰富的现场资料，为今后高等级公路建设积累了宝贵的经验和数据。更多还原

【Abstract】 With the rapid development of the road constructions in our country, the slope stability analysis and ecological protection design of rocky slope of highway are of great importance in highway building in hilly area. In this paper, it is thoroughly discussed that rock slope stability of rocky highway surface protection of rocky slope, which bases on the research project of the second-class highway between Gui Yang county and Jia He county. Hunan University and Chen Zhou Classified Highway Construction Limited Company have operated the research project. The theme-group discusses systematically and thoroughly the research on rocky slope stability analysis and ecological protection design.By analyzing rocky slopes built at home and abroad, the theme-group not only summarizes the analysis methods of rocky slope and ecological protection, but also points out some questions which have not been solved yet. Considering the characteristics of rocky slopes, this paper discusses the stability analysis of rocky slopes, the searching methods of its corresponding critical slip surface and the factors affecting the stability of rocky slope. On the basis of the experiences on ecological protection of slopes at home and aboard, this paper proposes a working way fitting for the second-class highway between Gui Yang county and Jia He county. It also discusses thoroughly the mechanism of ecological protection basing on the research. Besides, during the research period, combining theory of analysis with practice of building the road, the theme-group succeeds in the research on stability analysis and utilizes some new methods in building the second-class highway. In soil engineering experiment, the theme-group has obtained a lot of valuable datum which will be much helpful in building high-type highways in western China in the future.更多还原
