【摘要】 现阶段,高速公路建设是我国基础设施建设的热点和重点。我国是一个多山的国家,地质条件十分复杂。随着我国高速公路建设的高速发展,山区高速公路路堑边坡稳定性分析及防护技术已成为我国高速公路建设面临的关键技术之一。论文首先分析了山区高速公路路堑岩质边坡特点,对岩质边坡的失稳形式、破坏模式及影响因素进行了分析总结。其次对山区高速公路路堑边坡稳定性的分析方法进行了分析总结,指出各种方法的优缺点和适用条件,对边坡稳定性分析方法的选择提出了自己的观点；并分析了山区高速公路路堑边坡的设计原则、设计要素及各种边坡防护技术的适用性和防护机理,指出山区高速公路复杂路堑边坡应根据实际情况采用综合防护技术进行防护处理。最后,对依托工程汝郴高速公路K6+640左侧高边坡,采用边坡设计分析软件Slide对其原设计方案进行了稳定性分析和优化设计调整。工程应用结果表明调整后的优化方案合理可靠,对类似工程有一定的借鉴作用。更多还原

【Abstract】 In the present, construction of mountainous expressway is the main point of basic construction in our country. Our country is full of mountain, whose geological characteristic is very complicated. With the rapid development of expressway construction, the stability analysis and reinforcement method in the mountainous expressway construction become one of the most important techniques which will be faced during construction.The characteristic of the rock cutting slope in the mountainous expressway area is analyzed in the present paper, the unstable mode, failure mode and their influencing factor for the rock slope are summarized.Secondly, the stability analysis methods for the rock cutting slope in mountainous expressway are summarized, pointing out the advantages and disadvantages of each method as well as its adaptable conditions. The decision method for choosing the stability analysis method is proposed. Then the designing principle of rock cutting slope in the mountainous expressway area, its designing important factor, the adaptability of each slope reinforcement technique and its reinforcement mechanism are analyzed, pointing out that the comprehensive reinforcement techniques should be adopted according to the real situations, for the complicated characteristic of the rock cutting slope in the mountainous expressway area.Finally, the left side of the high slope in K6+640 location of the Nuchen expressway is chosen as the engineering background, the stability analysis and revised optimum designing are done to the initial designing scheme by according to the calculation results by the designing analysis software Slide. Due to the engineering application, it shows reasonable and reliable of the revised designing scheme, which will give some guidance for the real practice.更多还原
