` 本科毕业设计（论文）题目金堂三溪大道 3 标段设计学生姓名廖宽学 号1208010235教学院系土木工程与建筑学院专业年级土木工程 2025 级指导老师杨婷婷职 称讲师单 位西南石油大学辅导老师职 称单 位完成日期2025年6月1日摘要本次设计是对金堂县三溪大道第三标段的公路设计，金堂县三溪大道是一条二级公路，第三标段全长 2065 米，设计速度 60Km/h。采纳的是沥青混凝土路面，路面宽 7 米为双向两车道，硬路肩宽 1.5 米，路肩横坡度为-1.5％，路拱横坡度为 2％，路面全程设有超高，路面超高为 4％，不设加宽。全段道路设有4 个平曲线，2 个竖曲线，道路的平曲线设计满足使车辆行驶平稳，舒适的原则。道路进行了边坡稳定性验算，挡土墙设计，同时为了满足道路排水道路设计了六个涵洞，为了满足道路排水的需求所以对道路排水量进行计算确定涵洞的跨径，通过对金堂县当地水文条件的调查计算出了涵洞的参数。关键词：公路等级 ; 平曲线；纵断面；横断面；路基路面设计Abstract This design is a design for Contract No.3 of Sanxi Highway in Jintang, Sanxi Highway in Jintang is a secondary roads, I designed Contract No.3 total length of 2065 meters, the design speed of 60 km/h. I use the asphalt concrete pavement, for two-way two-lane road is 7 meters wide,Hard shoulder is 1.5 meters wide, shoulder horizontal gradient of 1.5%, road arch horizontal gradient of 2%, the road has high all the way, the road high at 4%, do not set widened. Entire section of road has four plane curve, two vertical curve, the road smooth plane curve design meet the vehicle, comfortable principle, at the same time plane curve can package to vertical curve, namely "flat bag vertical" principle. Road slope stability calculation, retaining wall design, at the same time in order to meet the road drainage road design six culvert, in order to meet the requirements of road drainage so to calculate and determine the span of culvert road displacement, through the survey of jintang county loca...
