摘要<br>公路边坡的治理对保护人民的生命财产，保证交通畅通具有重要意义。本工区的边坡治理及设计是作者以在四川省遂宁市农村公路路网建设项目一标段所收集到的资料为基础，结合本科阶段所学的理论知识及导师给的建议，根据相关的书籍和规范来完成的。治理前首先是对路堑边坡的稳定性进行评价，本设计采用了比肖普法进行计算边坡稳定性系数，计算出下滑推力。并根据规范要求将不同稳定性系数的边坡稳定性进行分类，对于被评价为不稳定的边坡应做出合理治理方案。目前治理公路高陡边坡的措施有喷锚网支护技术、抗滑桩墙体、锚杆支护等支挡结构。锚杆工程则由于具有适应性强、特别适用于许多滑面较深的滑坡，对滑坡稳定性和地质环境干扰小，可多桩同时施工，工区较短。本设计对边坡稳定性评价完成之后，根据岩土工程勘察报告和相关资料，通过分析比较，从三种可行性的方案中选取最优的支护方案——锚杆支护。然后，进行了锚杆设计计算，设计出合理的排水方案设计、护坡方案设计，、坡面绿化方案设计等方面的设计。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，制定出一个比较合理、科学的施工方案。最后编制了工程预算书，计算出本工程的工程预算总造价约为万元。

abstract<br>The treatment of highway slope is of great significance to protect people's life and property and ensure smooth traffic. The slope treatment and design of the work area is based on the data collected in the first bid section of rural road network construction project in Suining City, Sichuan Province, combined with the theoretical knowledge learned in the undergraduate stage and the suggestions given by the tutor, according to the relevant books and specifications. Before the treatment, the stability of the cutting slope is evaluated. In this design, Bishop method is used to calculate the slope stability coefficient and the sliding thrust. According to the requirements of the code, the slope stability with different stability coefficients is classified, and the reasonable treatment scheme should be made for the slope which is evaluated as unstable. At present, the control measures of highway high and steep slope include shotcrete anchor mesh support technology, anti slide pile wall, bolt support and other supporting structures. Because of its strong adaptability, anchor engineering is especially suitable for many landslides with deep sliding surface, which has little interference to landslide stability and geological environment. It can be constructed with multiple piles at the same time, and the work area is short. After the slope stability evaluation is completed, according to the geotechnical engineering investigation report and relevant data, through analysis and comparison, the optimal support scheme - bolt support is selected from the three feasible schemes. Then, the bolt design calculation is carried out, and the reasonable drainage scheme design, slope protection scheme design and slope greening scheme design are designed. The design results of the project are obtained. The detailed construction organization design is also carried out in the design, and a more reasonable and scientific construction scheme is formulated. Finally, the project budget is prepared, and the total cost of the project budget is about 10000 yuan.<br>
