杭瑞高速公路岳阳至常德K12+600~K14+700路基路面综合设计
摘要
根据设计任务书提供的设计资料和设计要求以及交通部颁发的标准和规范对杭瑞高速公路岳阳至常德K12+600~K14+700段进行路基路面综合设计路基路面综合设计。
此次设计主要内容包括:路线设计、路基、路面设计,桥梁、涵洞设计,外文文献翻译,专题研究,计算机程序编制。根据提供的路线原始资料,考虑土石方填挖平衡、最大纵坡、最小纵坡、坡长、高程控制点等因素进行纵断面设计,由此结合平面图进行横断面设计。根据设计段内的地形状况,设置了排水沟、急流槽、圆管涵等排水设施。同时,进行挡土墙设计计算和防护工程设计,设置加筋土挡土墙,采用植草皮、砼预制块等多种形式进行边坡防护。高填路堤路段采用修筑挡土墙的方法收缩坡脚,减少填方,增加路堤边坡稳定性;利用BISHOP法进行了稳定性验算。进行了沥青混凝土路面的设计和水泥混凝土路面的设计,由给定的交通量等条件,按照路面结构组合设计的原则,选用不同路面结构层厚度和材料进行结构设计验算,并进行了方案比选。
通过本次毕业设计,我掌握了纬地、CAD等各类工程软件的应用,对Word、Excel等办公软件功能有了进一步的熟悉;而且在专业知识方面得到了综合训练和提高,增强了独立分析问题和解决问题的能力。

THE COMPREHENSIVE DESIGN ON SUBGRADE AND PAVEMENT FROM K12+600 TO K14+700 OF HANG RUI FREEWAY BETWEEN YUEYANG AND CHANGDE
ABSTRACT
According to the design information,demands of the design task instrument,the technical standards and specifications for freeway design published by the Ministry of Communications of China, the comprehensive design of freeway subgrade and pavement from K12+600 to K14+700 has been carried out based on the data of Hangrui freeway between Yueyang and Changde.
Our prime contents of the design project includes freeway route design, the design of pavement,the design of the bridges and culverts,translating an English article into Chinese,special study and compile a simple computer programme. According to route firsthand information that is offered ,we must keep the balance between the diging of filling out,maximun vertical slope,minimum vertical slope, the length of slope,high control point,etc. During designing the vertical section and combining the plane figure ,we design the cross section. According to the condition of climate district and remiting calculation water of quantity,set up drainage system which includes side ditch, intercepting ditch etc. Meanwhile, do block design of wall of soil calculate and protect engineering design , set up the reinforced retaining walls to go on, adopt plant turf to protect the slope ,etc. In high embankment highway section, shrink slope foot by building the retaining wall, reduce the filling, increase the slope stability; make use of BISHOP to follow the checking stability calculation. Do the design which has carried on the asphalt concrete road surface and design of the cement concrete road surface by giving volume of traffic definitely terms, according to the design principle of the road surface structure,select for different road surface structure layers of thickness and material then carry on structural design checking computations, and do scheme comparison..
Through graduation project,not only know of CAD,Hint 5.8 ,but also practice the ability to use office software like Word、Excel. The specialized knowledge and technologe have been comprehensively applied and improved ,and the perspective of solving problems had been enhanced.
