1、摘要本設(shè)計(jì)是從信陽到商城某段二級(jí)公路的設(shè)計(jì),該段路線總長為3054m。本設(shè)計(jì)中設(shè)計(jì)車速為80km/h,雙向兩車道。本設(shè)計(jì)是在對交通量進(jìn)行分析,查找相應(yīng)的技術(shù)規(guī)范的基礎(chǔ)上,確定出公路的技術(shù)等級(jí)以及設(shè)計(jì)需要的各種參數(shù),最終確定采用二級(jí)公路的技術(shù)指標(biāo)進(jìn)行設(shè)計(jì)。結(jié)合周圍的地形情況進(jìn)行了平面線形設(shè)計(jì),平面線形中有三個(gè)轉(zhuǎn)角??v斷面的設(shè)計(jì)中有兩個(gè)豎曲線,滿足平縱線形組合設(shè)計(jì)中的各種要求。在橫斷面的設(shè)計(jì)中,確定了橫斷面組成及各種要素后,繪制出橫斷面圖。本設(shè)計(jì)中路面設(shè)計(jì)采用瀝青路面進(jìn)行設(shè)計(jì),主要包括結(jié)構(gòu)層的擬定和設(shè)計(jì)層厚度計(jì)算。涵洞設(shè)計(jì)主要是在擬定結(jié)構(gòu)尺寸后進(jìn)行各種強(qiáng)度的
2、驗(yàn)算。設(shè)計(jì)中結(jié)合地形及周邊環(huán)境條件,通過兩條線路方案的比選,最終確定最佳方案。關(guān)鍵詞:二級(jí)公路;縱斷面;橫斷面;瀝青路面;涵洞2AbstractThisdesignisasecondaryroaddesignfromXinyangtoShangchengandthetotallengthofthesectionis3054m.Thedesignspeedis80km/handtheroadhastwolanes.TheTparameterswhichareneededinthedesignaredefinedbyanalyzingthetraffican
