娄底至衡阳高速公路K25+251.588--K26+040路段 综合设计 摘 要：根据设计任务书以及现行颁布的标准和规范对娄底至衡阳的高速公路K25+251.588——K26+040路段进行了路基路面综合设计。本设计路线全长0.788公里，路基宽27m ,双向四车道，设计车速100km/h。 首先根据已定的路线平面图，进行纵断面设计。纵断面设计时应符合规范要求，比如说合理的坡度，平、纵组合设计等问题。结合平、纵断面完成路基横断面设计，得出土石方表，进行土石方调配。接着边坡稳定性分析、边坡防护设计、挡土墙设计、路基路面排水设计、涵洞设计和路面设计。路面设计包括沥青路面设计和水泥混凝土路面设计,并画出路面结构图，然后完成路基路面工程的预算，最后完成施工组织设计及施工进度计划横道图。 此次设计主要采用的方法主要有：利用CAD绘制施工图，使用纬地道路系统进行路线综合设计，纵横概预算软件计算工程预算，简单的办公软件记录表格、文件。 关键词：高速公路；路基；路面；概预算；施工组织；综合设计 The Synthetical Design of Loudi -Hengyang Freeway From K25+251.588 to K26+040 Abstract: According to the design plan and the existing standards and norms issued ，the synthetical design of Loudi -- Hengyang freeway subgrade and pavement from K25+251.588 to K26+040 has been carried out . The length of the freeway is 0.788 km，the subgrade width is 27 m , and four-lane two-way , the design speed is 100 km/ h . First of all, according to the plane which is preseted , I carry out the profile design. Profile Design should meet the standards, such as a reasonable slope, flat vertical combination of design and other issues. Having finished the cross section which is combining the plane and the profile，I make out the number of earth and deploy the earth .Then slope stability is analysed, the slope protection is designed ,the retaining wall and the drainage of the road embankment are designed, I design the culvert and the pavement design. The design of the main methods used are: construction drawings using CAD drawing, using the latitude line of road system for integrated design, vertical and horizontal budget estimate software to calculate the project budget, a simple office software record forms, documents.
