山区高速公路初步设计说明书

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统计和计算数据及其使用任务和性质，将道路等级确定为高速公路。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。结合当地自然状况及规范规定，进行线路平面设计、纵断面设计、路基设计以及横断面设计。此外对线路支挡防护、排水及土石方调配进行初步设计。设计最终资料包括平纵横、路基设计、线路防护排水及土石方设计图表。本线全线总长18643.831m。有9个平曲线、9个竖曲线、涵洞17道，桥梁2座，设计车速100km/h，路基宽度26m。本设计中主要运用了纬地5.88公路选线设计软件、纬地土石调配软件及东南大学路面设计软件进行相应各项的设计。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AbstractThedesignisapreliminarydesignofcertainpartialofanewwaywhichlocatedinShandongprovince.Accordingtothestatisticalandcalculateddateaboutthetrafficofthedesigningway,theusetasksandnature,thelevelfortheroadisdeterminedhighway.ShandongprovincelocatedineastChinaandYellowRiverdownstream.Routethroughthehillyarea.Combinedwiththelocalnaturalconditionandtherulesandregulations,doplanedesign,longitudinaldesign,roadbeddesignandcross-sectionaldesign.Inadditiontotheroadretainingprotection,drainageandearthallocationdopreliminarydesign.Theeventuallydesignmaterialincludingplane,longitudinal,cross-sectional,roadbeddesigningcharts,roadprotection,drainageandearthallocationdesigningcharts.Atotallengthoftherouteis18643.831meters.Thereare9horizontalcurves,9vertical,17culvertsandtwobridgesintheroute.Thelanedesignat100Kmperhour,andthewidthofsubgradeis26meters.Themainsoftwareusedinthedesignfollowing:HintCAD5.88tohighwayroutedesignsoftware,TsfdpV2.5toearth-rockallocatesoftware,Asphalttopavementdesignsoftware.KeyWords:themiddleareaofShandong,Mountainousandhillyregion,Highway,lineardesign,subgrade,pavement,drainageii目录1设计技术标准的确定.............................................................................................11.1中国公路发展现状..............................................................................................11.2该公路的设计意义..............................................................................................21.3沿线气候，降水，水系，及地形地貌特征......................................................31.3.1气候..............................................................................................................31.3.2降水..............................................................................................................41.3.3水系..............................................................................................................41.3.4地形地貌......................................................................................................41.4道路等级和主要技术指标的论证和确定..........................................................51.4.1交通量计算及公路等级的选用..................................................................51.4.2主要技术指标..............................................................................................62路线设计.................................................................................................................82.1平面设计的要求..................................................................................................82.1.1平面线形的均衡与连贯..............................................................................82.1.2避免连续急弯的线形..................................................................................82.1.3平曲线长度..................................................................................................82.1.4曲线间直线最小长度的要求......................................................................92.2圆曲线设计..........................................................................................................92.2.1圆曲线最大半径..........................................................................................92.2.2圆曲线选用要求..........................................................................................92.2.3特殊要求......................................................................................................92.3缓和曲线设计....................................................................................................102.3.1缓和曲线的有关规定................................................................................102.3.2缓和曲线的长度选用................................................................................102.4本线路平面详细设计........................................................................................112.4.1平曲线要素值的确定................................................................................112.4.2纬地软件平面设计....................................................................................122.5本线路纵断面详细设计....................................................................................132.5.1建立数模....................................................................................................132.5.2纵断面地面线数据输入............................................................................162.5.3纵断面动态拉坡设计................................................................................162.5.4路线纵断面绘图........................................................................................182.5.5本设计中竖曲线主要参数........................................................................193路基设计...............................................................................................................203.1路基防护设计............................................................
