摘 要

本設(shè)計根據(jù)給定的資料，通過對原始數(shù)據(jù)的分析,根據(jù)該路段的地質(zhì)、地形、地物、水文等自然條件,依據(jù)《公路工程技術(shù)標(biāo)準(zhǔn)》 、《公路路線設(shè)計規(guī)范》等交通部頒發(fā)的相關(guān)技術(shù)指標(biāo),在老師的指導(dǎo)和同學(xué)的幫助下完成的。
設(shè)計內(nèi)業(yè)詳細(xì)資料有：路線設(shè)計，包括紙上定線（山嶺區(qū)或越嶺線）、繪制路線平面圖、路線縱斷面設(shè)計）；路基設(shè)計，完成兩公里橫斷面和路基土石方的計算及路基排水設(shè)計；路面設(shè)計，水泥混凝土路面設(shè)計；小橋涵設(shè)計，完成一項涵洞設(shè)計；路線交叉設(shè)計，完成一項路線平面交叉；設(shè)計概算編制，完成全線設(shè)計路段的初步設(shè)計概算；應(yīng)用計算機(jī)繪制工程圖，按老師指導(dǎo)和要求完成。
整個設(shè)計計算了路線的平、縱、橫要素,設(shè)計了路基、路面、平面交叉、小橋涵的尺寸等內(nèi)容,由此圓滿完成了北翠公路青年農(nóng)場至前進(jìn)段兩階段初步設(shè)計。

關(guān)鍵詞：路線，路基,路面,涵洞，平面交叉，概算

ABSTRACT
Data that this design according to give to settle to complition, complete the Threexin forest of Mulin to lianhe highway station segment (1) first design station segment (2) the relevant technique index sign for kind, geography for second class highway route, from this design learning a lot of knowledge concerning highways, passing analysis primitive dataing, according to the road's segment, characteristics of term nature, such as, ground thing, and hydrology etc., Basis highway engineering technique standard , highway route designing the normal waiting the transport, and complete to design under the help that the teacher's leading is with the classmate of constitute the circumstance,
The design inside of stage first steps include: Route design,The paper up settles the lines( mountain range area, or more mountain range line),Draw the route plane chart, Proceed route vertical section of design;Roadbed design, Complete two kilometer cross sections are with the roadbed the calculation of square ground and roadbed drain the design;Road design, Cement concrete road design;Small bridge culvert design, Complete the design of a culvert;The route crosses the design, Complete a route flat surface to cross; Design budgetary estimate establishment: Completes the entire line todesign the road section the preliminary design budgetary estimate;The application calculator draws the engineering diagram, Complete under the teacher's leading request.
we compute the route even, vertical , horizontal main factor, designed the flat surface to designtheroadbed,roadthesizefor, small bridge culvert, fromhere,successfully completed Qingnian to Qianjin of the Beicui highway in section two stages preliminary designs.

Key words: Route, roadbed, road, culvert，Route cross，Budgetary estimate
