1、邵阳学院毕业设计(论文)摘要本毕业设计课题为某一级公路K84+000-K86+000段施工图设计。本路段经过地区总体地势起伏不大，为典型的平原微丘区地形一级公路，线性平坦。公路全长2km，设计时速为100km/h。路基宽26m，有4个行车道，每个行车道是3.75m，中央分隔带宽2ｍ,中间带宽3.5m,硬路肩宽3m,土路肩宽0.75m。本设计包括几何设计和结构设计。在几何设计中，又包括平面设计、纵断面设计、横断面设计。本段路线平曲线共有交点1个，曲线半径最小为1500m，最小缓和曲线长度为140m，整段路没有采用极限平曲
2、线半径，是基本型曲线。路线最大纵坡为2.93%，在结构设计中，又包括了路基路面设计、涵洞设计、防护工程设计。路面采用混凝土路面，垫层为15cm厚的天然砂砾，基层为15cm厚水泥稳定碎石，面层为25cm厚水泥混凝土。本设计包括2个涵洞设置。防护工程除按装工程需要，只包括护坡设计。除几何设计和结构设计外，本设计还包括了工程量的计算和施工图预算。关键词：一级公路；几何设计；结构设计；工程量的计算；施工图预算54邵阳学院毕业设计(论文)AbstractThesubjectofgraduationdesignisaconstr
