内容摘要内容摘要本设计为山东省境内新建公路某段的初步设计根据设计公路的交通量及其使用任务和性质，确定为高速公路山东省地处中国东部、黄河下游，路线所经地形为山地丘陵区本线全线总长 18643.831m有 9 个平曲线、9 个竖曲线、涵洞 16道，桥梁 2 座，设计车速 100km/h，路基宽度 26m路面为沥青混凝土结构本设计说明书进行路线方案的论证，确定合适的设计方案，并推荐一个最佳方案进行详细的技术设计，包括路线的平、纵、横设计，路基路面设计和排水设计，环境评价等各方面内容设计内容主要包括：运用纬地软件进行道路平、纵、横断面的设计；运用纬地土石方可视化调配系统进行土石方的调配；运用东南大学沥青混凝土路面设计软件进行路面结构设计，同时完成了各种图、表的绘制及计算关键词关键词：山东中部，山地丘陵，高速公路，平、纵、横设计，路基，路面，排水, 沥青混凝土AbstractThe design is a preliminary design of a new way in Shandong Province. It is defined a highway because of the way’s traffic volume, using task and character. and the route through the plain terrain micro-Hill. Shandong is located in eastern China, Yellow River, and the route through the plain terrain micro-Hill. A total length of the route is18643.831metres.There are 9 horizontal curves,9 Vertical Curve,16culert and two bridge in the route. The lane design at speeds of 100 km per hour, and the width of subgrade is 26 metres. The pavement is bituminous concrete structure. Design elements is to use Hint CAD to Complete road flat, vertical, cross-sectional design and use TsfDp V2.5 to Complete Earthwork allocation. We can also use asphalt concrete pavement design software of Southeast University to Complete Pavement Structure Design.Key Words: the middle area of Shandong, the highway, linear design, subgrade, pavement, drainage, asphalt concretei i 目目 录录 1 设计技术标准的确定....................................................................................................1 1.1 中国公路发展概况.....................................................................................................1 1.1.1 公路发展概况.....................................................................................................1 1.1.2 公路建设概况：.................................................................................................2 1.1.3 我国高速公路发展概况.....................................................................................2 1.2 该公路的设计意义.....................................................................................................4 1.3 沿线地貌，地形，地质，及自然地理特征.............................................................4 1.3.1 气候特点.............................................................................................................4 1.3.2 降水量.................................................................................................................5 1.3.3 水系.....................................................................................................................5 1.3.4 地形地貌.............................................................................................................6 1.4 道路等级和主要技术指标的论证和确定.................................................................7 1.4.1 交通量计算及公路等级的选用........................................................................7 1.4.2 主要技术指标.....................................................................................................8 2 路线设计......................................................................................................................11 2.1 路线平面设计...........................................................................................................11 2.1.1 概述...................................................................................................................11 2.1.2 选线的步骤和方法...........................................................................................12 2.1.3 路线方案的选择...............................................................................................13 2.2 定线操作步骤...........................................................................................................14 2.3 平面设计的要求.......................................................................................................15 2.3.1 平面设计满足的要求.......................................................................................15 2.3.2 平面线形的均衡与连贯...................................................................................16 2.3.3 避免连续急弯的线形.......................................................................................16 2.3.4 平曲线长度.......................................................................................................16 2.3.5 曲线间直线最小长度的要求...........................................................................17 2.4 圆曲线设计...............................................................................................................17 2.4.1 一般规定...........................................................................................................17 2.4.2 不设超高的圆曲线最小半径...........................................................................17 2.4.3 圆曲线最大半径...............................................................................................17 2.4.4 圆曲线选用要求..................。
