【正文】 洛陽(yáng)理工學(xué)院畢業(yè)設(shè)計(jì)（論文） I 偃師龐村至伊河南段公路施工圖設(shè)計(jì) 摘 要 本論文主要介紹了偃師龐村至伊河南段公路 施工圖 的設(shè)計(jì)過(guò)程 , 根據(jù) 該路段的 地質(zhì)、地形、地物、水文 、交通量及其增長(zhǎng)率 等 資料， 依據(jù)《 公路工程技術(shù)標(biāo)準(zhǔn)》、《公路路線設(shè)計(jì)規(guī)范》等交通部頒發(fā)的相關(guān)技術(shù) 標(biāo) 準(zhǔn) ,在老師的指導(dǎo)和同學(xué)的幫助下完成的。 該路段所經(jīng)地區(qū)是平原微 丘區(qū)，根據(jù) 交通量 及其增長(zhǎng)率將該路 設(shè)計(jì)成設(shè)計(jì)速度為 80km/h 的雙向四車道Ⅰ 級(jí) 公路，路線全長(zhǎng) 米，路基寬度為 米，共設(shè)有 2個(gè)平曲線， 4個(gè)豎曲線 。 設(shè)計(jì)內(nèi)容包括平面設(shè)計(jì)、縱斷面設(shè)計(jì)和橫斷面設(shè)計(jì)；之后進(jìn)行 排水設(shè)計(jì) ，設(shè)置了圓管涵等構(gòu)造物， 確保 路基路面的水穩(wěn)定性 ； 最后完成了 路面結(jié)構(gòu) 層 的組合設(shè)計(jì) 等內(nèi)容。 關(guān)鍵詞： Ⅰ級(jí)公路，平面設(shè)計(jì)，縱斷面，橫斷面， 組合設(shè)計(jì) 洛陽(yáng)理工學(xué)院畢業(yè)設(shè)計(jì)（論文） II The construction design for the highway of Pang village Yanshi to Yi river ABSTRACT This paper mainly introduces the design process of highway construction that is from Pang village Yanshi to Yi river, according to the sections of the geology, topography, terrain, hydrology, traffic volume and its growth rate data, on the basis of technical standard of Highway Engineering, highway route design specification, issued by the Ministry of munications and relat, pleted it with the help of teachers and students. The road through the area is the area of hill plain, according to the volume of traffic and the growth rate of the road design into the design speed is twoway four driveway grade I Highway 80km/h, line length of meters, subgrade width of meters, with a total of 2 curves, 4 vertical curve. The design includes plane design, longitudinal section design and cross section design。 after pled the design of drainage, set up the circular pipe culvert structures, ensure that the water stability of subgrade and pavement。 finally pled the bine design of the pavement structure .
