摘要

随着工程技术的不断发展，在实际的道路工程和建筑工程中涉及到大量的边坡问题，因而对边坡工程的处理是一项重要的内容。根据不同的边坡破坏形式,边坡的治理应采取不同的计算方法与治理措施。目前治理公路高陡边坡的措施有SNS柔性防护技术、喷锚网支护技术、抗滑桩墙体系等支挡结构。抗滑桩支护是加固治理滑坡的一种行之有效的方法，它施工简便、快速、加固效果好，己经在世界各国的滑坡治理中得到比较广泛的应用。

本设计是以在重庆市城口至万源快速公路通道第CW12合同段K0+000～K0+500段边坡的工程地质勘察报告资料为基础，结合本科所学的理论知识以及导师的指导建议，根据相关书籍和规范来完成的。本设计首先对边坡进行稳定性分析，判定该边坡的稳定程度，再根据工程勘察报告和相关资料，进行了抗滑桩的设计计算，得出了本工程的设计结果。设计还进行了详实的施工组织设计，制定出了一个比较合理、科学的施工方案。

Abstract：With the continuous development of engineering technology, in the actual road and construction works related to a lot of slope problems, so how to deal with the Slope engineering is an important content. According to different Failure modes of the slope, the slope of governance should be taken to the different methods of calculation and control measures. Measures of governance highway steep slope include the SNS flexible protection technology, puffanchor support tecthnology, anti-slide pile wall system retaining structures,and so on. Stabilizing piles supporting is an effective method of Landslide treatment which is simple, fast, good reinforcement effect for construction, It has already been widely used to deal with Landslide in the world.

The design is based on engineering geological investigation report information in theCW12 contract segment of Chongqing City Chengkou to Wangyuan expressways channel ,slope of K56 +600 ~ K56 +800 .Use the theoretical knowledge as well as recommendations for the guidance of instructors, according to the books and norms. The design′s first job is to analyse stability of the slope to determine the stability of the slope, and then ,according to the engineering investigation report and related information to design Friction Pile and obtained the results of the engineering design. The design also carried out a detailed construction design, worked out a rational, scientific construction program.

Key words : Slope stability analysis, highway landslide prevention, anti-slide pile
