1、摘要本毕业设计课题为邵新路A5合同段(K31+600-K35+100段)施工图设计。本路段经过地区总体地势起伏较大,为典型的山岭微丘区地形二级公路,但由于选线合理,沿着山谷走向,因此路段经过的地区较为平坦。公路全长2.5km,由于地形的限制,设计时速为40km/h。路面宽7m,路基宽8.5m,路面两侧为0.75m的土路肩。本次设计分别对此公路段进行了几何设计和结构设计。在公路几何设计中,分别进行了平面、纵断面、横断面设计。本段路线平曲线共有交点5个,平均每公里约1.43个,曲线半径最小为100m,最小缓和曲线采用40m,没有采用极限平曲线半径。公路没有设置S型曲线,都是简
2、单曲线。路线最大纵坡为0.809%,在公路结构设计中,分别进行了路基路面设计、涵洞设计、防护工程设计。经过交通分析,路面形式采用混凝土路面。垫层为15cm厚的天然沙砾,基层为15cm厚水泥稳定碎石,面层为24cm厚水泥混凝土;本段公路设计了4个涵洞。防护工程按工程需要,只包括护坡设计。除了几何设计和结构设计外,还进行了工程量的计算,并进行了施工图预算。关键词:二级公路;几何设计;结构设计;工程量的计算;施工图预算AbstractThegraduationprojectfortheShaoXinroadoftheContractSection--A5(K31+600-K35
