摘要PAGEII偃师顾县至黄蟒崖段公路施工图设计摘要偃师顾县至黄蟒崖段公路路线起点连接G310、省道S320顾龙线，是洛阳至偃师的主要交通要道。它的建成对全国公路网络结构的完善，对加快城市与城市之间经济社会发展具有极其重要的意义。拟建的偃师顾县至黄蟒崖段公路，经过区域地貌为伊南洪积冲积坡地、伊洛河冲积平原、洛河川区、洛阳中部黄土丘陵区，整个地形起伏不大，全长3.949km。根据规范要求，结合当地实际情况，全线采用双向四车道一级公路标准，沥青路面，设计速度80km/h，路基宽度24.5m。本设计研究的内容包括：首先，根据交通量确定车道数，并在地形图上选线、定线，然后进行道路平面设计，纵断面设计，横断面设计，桥涵设置等。此外还对该路段的路基、路面等进行了设计。关键词：一级公路，选线，路基，沥青路面，涵洞ThedesignofhighwayconstructionfromYanshiGuxiantoHuangmangyaABSTRACTThehighwayroutefromYanshiGuxiantoHuangmangyawhichstartingpointisconnectedwiththeG310highwayandprovincialhighwayS320Gulongline,isthemaintrafficroutesfromLuoyangtoYanshi.Itsbuilthasanextremelyimportantsignificancetoimprovethenetworkstructureofnationalhighwayandtospeeduptheeconomicandsocialdevelopmentamongcities.TheproposedhighwayofYanshiGuxiantoHuangmangyathroughtheregionallandscapewhichconcludeEinonfloodalluvialslope,YiluoRiveralluvialplain,plainarea,LuohecentralLoessHillyAreaofLuoyang.TheHYPERLINK"http://dict.baidu.com/s?wd=landform"landformislittleupsanddownsanditsfull-lengthis3.949km.Accordingtothestandardrequirements,combinedwiththelocalactualsituation,allusethetwo-wayandfourlanehighway,asphaltpavement.Thedesignspeedis80km/handtheroadbedwidthis24.5m.Thedesignofthestudycontentsinclude:firstly,consideringtrafficvolumetodeterminethenumberofthetolllanes,andselectlinesanddecideonthetopographicmapandthenroaddesign,designandverticalsectiondesign,crosssection,bridgeandculvertsettings.Inaddition,theroadbedandpavementofthissectionarealsodesigned.KEYWORDS：thearterialroad，lineselection，theroadbed，asphaltpavement，culvert前言目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc359226661"前言PAGEREF_Toc359226661\h1HYPERLINK\l"_Toc359226662"第1章绪论PAGEREF_Toc359226662\h2HYPERLINK\l"_Toc359226663"1.1沿线地理条件PAGEREF_Toc359226663\h2HYPERLINK\l"_Toc359226664"1.2沿线气象资料PAGEREF_Toc359226664\h2HYPERLINK\l"_Toc359226665"1.3设计任务PAGEREF_Toc359226665\h2HYPERLINK\l"_Toc359226666"1.4设计成果PAGEREF_Toc359226666\h2
