摘 要

近年来，中国基建高歌猛进，已经成了国际上的一个名片。高速公路作为经济发展中的一个重要加速器，近年来得到了长足的发展，通车里程已经跃升到了世界第一。然而由于我国多山的地形条件，在公路的建设工程中，各种复杂的滑坡以及边坡的变形破坏成为了道路建设人员经常面临的一个问题。 路堑边坡失稳的危害巨大，轻则造成经济损伤，重则危害道路安全，造成人员伤亡。因此如何对路堑边坡进行安全整治是需要我们探究的课题。

本文中我们通过学习前人提出的一些整治边坡的手段和经验和结合具体事例，分析了某路堑边坡滑坡发生后，如何对该边坡进行分析与整治并保证治理后的边坡的长期稳定和安全。此次的工程实例，我结合当地的地形地质条件以及边坡稳定分析计算的结果，最终采取了削坡减载的方案实现边坡滑坡后的稳定，并且提出了具体的解决方案和工程措施。

在边坡整治的研究当中，边坡稳定性分析是解决该问题的核心，从而使我们能够分析已有边坡的稳定程度。之后，便可以为拟定经济合理的边坡开挖方案以及加固方案提供支持。由于简单易行，我们经常使用极限平衡法来对边坡稳定进行分析，通过抗滑力和下滑力的主要矛盾来弄清楚我们遇到的边坡问题。

关键词：边坡整治 ，极限平衡法，削坡减载

Abstract

In recent years, Chinese infrastructure has become a stride forward singing militant songs, name card in the world. As an important accelerator in the economic development, the expressway has made great progress in recent years, and the mileage has reached the first place in the world. However, due to the mountainous terrain in China, a variety of complex landslides and deformation of the slopes become a common problem for road construction workers. The damage of cutting slope instability is enormous, light causes economic damage, heavy road safety, causing casualties. Therefore, how to carry out safety control of cutting slopes is a subject that we should explore.

In this paper, we put forward some improvement through learning slope means and experience and combining with concrete examples, analysis of the occurrence of a cutting slope, the slope of how to analyze and remediation and ensure long-term stability and safety of the slope. In this project, I combined with the calculation results of local topographic and geological conditions and slope stability, finally adopted cutting slope and reducing load for landslide stability after, and puts forward specific solutions and measures.

In the study of slope regulation, the slope stability analysis is the core to solve the problem, so that we can analyze the stability of the existing slope. After that, it can provide support for the economic and reasonable slope excavation scheme and reinforcement scheme. Because of the simplicity, we often use the limit equilibrium method to analyze the slope stability. Through the main contradiction between the sliding force and the glide force, we can find out the side slope problems we encounter.

Key words: Slope regulation ，Limit equilibrium method，Slope reduction and load reduction
