摘 要

改革开放以来，中国基建进行得是如火如荼，老城市追求伟大复兴，新城市急不可耐的冉冉升起，随处可见各种各样的工程建设，虽然有些污染环境，但是也是城市发展所必需的。中国有句老话，要致富，先修路。这句话言简意赅地指出了修路在经济发展中举足轻重的地位。国内基建已经取得了卓越的成就，取得的技术突破更是数不胜数，在交通建设方面，中国的国道经历了一次又一次整修，如今已是宽阔平坦的致富大道，纵横交错的高速公路更是把中国大大小小的城镇全部连接起来，无论去哪里，都可以自由飞驰，无比便捷 。高速公路近年来已经有了跨越性发展，通车里程更是跃居世界第一。然而，发展的同时，也会遇到许多艰难险阻，由于我国幅员辽阔，地形复杂多样，山地较多，所以在高速公路建设中，难免碰到许许多多需要穿山越岭的工程，同时也就伴随着路堑边坡的设计和防护问题，各种各样复杂的滑坡以及边坡的变形真的是对公路安全危害巨大，不仅威胁到行车人的生命财产安全，也威胁到公路的正常运行。因此，我们亟需探讨研究路堑边坡的稳定性，以确保安全。这篇论文的题目就是：路堑边坡稳定性分析。这篇论文通过查阅前辈们的杰作，学习路堑边坡稳定性分析的方法，学习保证路堑边坡稳定性的措施，并且结合潭邵高速公路路段的具体实例，分析了某路段边坡的稳定性，并且给出治理措施和保证边坡长期安全稳定的方法。这次的工程实例，根据当地山体的地质地貌情况，我们采取了削坡减载的方法，给出了具体的解决方案和施工方法。在这个方案中，边坡稳定性的分析方法是核心，只有分析得出目标地的边坡稳定性之后，才能得出经济合理的解决方案。分析方法有许多，由于极限平衡法简便易用，我们采用极限平衡的方法来分析下滑力和抗滑力的情况，从而解决问题。

关键词：高速公路，边坡整治，极限平衡，削坡减载，经济合理

Abstract

Since the reform and opening up, China's infrastructure has been in full swing. The old cities are pursuing a great renaissance, the new cities are rising in a hurry, and there are various kinds of construction projects everywhere, although some of them pollute the environment. But it is also necessary for urban development. There is an old Chinese saying that in order to get rich, build roads first. This sentence points out to the point that road building plays an important role in economic development. Remarkable achievements have been made in domestic infrastructure construction, and numerous technological breakthroughs have been made. In terms of transportation construction, China's national roads have been renovated again and again, and are now a broad and flat road to prosperity. The crisscross highway China's large and small towns are all connected, no matter where to go, can fly freely, incomparably convenient. Expressway has already had leapfrog development in recent years, traffic mileage is leapt to the first place in the world. However, at the same time of development, there will be many difficulties and difficulties. Because our country has a vast territory, diverse terrain and many mountainous regions, we will inevitably encounter many projects that need to cross the mountains in the construction of highways. At the same time, along with the design and protection of cutting slope, all kinds of complex landslide and slope deformation are really great harm to highway safety, not only threaten the safety of the driver's life and property. It also threatened the normal operation of the highway. Therefore, we need to study the stability of cutting slope to ensure safety. The title of this paper is: slope stability analysis. In this paper, by referring to the masterpieces of the predecessors, learning the methods of stability analysis of cutting slopes, learning the measures to ensure the stability of cutting slopes, and combining with the concrete examples of the section of the Tan-Shao Expressway, the paper analyzes the stability of a certain section of the slope. The measures and methods to ensure the long-term safety and stability of the slope are also given. According to the geological and geomorphological conditions of the local mountain body, we have adopted the method of slope cutting and load reduction, and given the concrete solution. Determination of plans and construction methods In this scheme, the analysis method of slope stability is the core. Only after analyzing the slope stability of the target land, can the economic and reasonable solution be obtained. There are many analytical methods, because the limit equilibrium method is simple and easy to use, we use the limit equilibrium method to analyze the situation of the sliding force and the anti-slide force, thus solve the problem.

Key Words : highway , slope regulation , limit balance , slope reduction and load shedding，economic reasonable
