摘 要
　　　
本設(shè)計主要完成了湖北省宜昌某地區(qū)新建二級公路的設(shè)計，根據(jù)給定的資料，通過對原始數(shù)據(jù)的分析,以及該路段的地質(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),設(shè)計了以路線、路基、路面，以及涵洞、土石方調(diào)配、路基排水防護(hù)，交通安全設(shè)施等內(nèi)容為主的道路。
　　　
依據(jù)遠(yuǎn)景交通量將路線設(shè)計成設(shè)計速度為60km/h的雙向行車道二級公路，路線全長3666.11米，路基寬度為10米，共設(shè)有5個平曲線，5個豎曲線。
　　　
路線部分包括平面、縱斷面及橫斷面的設(shè)計。首先進(jìn)行了紙上定線及修正導(dǎo)向線繪制，經(jīng)比選確定最優(yōu)方案；其次，根據(jù)平面結(jié)合當(dāng)?shù)氐牡匦?、氣候、環(huán)境因素進(jìn)行了縱斷面設(shè)計；最后選定1km進(jìn)行橫斷面設(shè)計，并繪制橫斷面圖，計算土石方。路基設(shè)計中考慮超高和加寬計算，并進(jìn)行了排水防護(hù)設(shè)計。根據(jù)交通組成及發(fā)展趨勢結(jié)合當(dāng)?shù)刂方ú那闆r進(jìn)行路面結(jié)構(gòu)設(shè)計，經(jīng)綜合考慮對全線確定了防護(hù)及排水工程的結(jié)構(gòu)尺寸、類型、位置，沿線涵洞進(jìn)行了初步結(jié)構(gòu)設(shè)計，以及基本的交通安全設(shè)施。公路工程造價設(shè)計中綜合考慮施工，進(jìn)行了初步的概算，造價總金額為4056408元。
　　　
整個設(shè)計計算了路線的平、縱、橫要素,設(shè)計了路基、路面、小橋涵等內(nèi)容,由此圓滿完成了江西贛州某新建二級公路初步設(shè)計。

Abstract

The design is mainly carried out in an area of Yichang new secondary road design, according to the information given by the analysis of the raw data, as well as the section of the geology, topography, terrain, hydrology and other natural conditions, according to the "Highway Engineering technical standards "," highway route design "issued by the Ministry and other traffic-related technical indicators, designed to route, roadbed, road and culvert, earthwork allocation, subgrade drainage protection, traffic safety facilities and other content-based way.
　　　
Vision will route traffic based on a design speed of design 60km / h lane two-way roads, the route length of 3666.11 meters, roadbed width of 10 meters, a total of five horizontal curve, five vertical curve.
　　　
Section of the route, including plan, profile and cross-sectional design. First carried out on paper alignment and correction-oriented line drawing, by comparison to determine the optimal solution; Secondly, according to plane combines local topography, climate, environmental factors were longitudinal design; finally selected 1km conduct cross-sectional design and draw cross-sectional diagram, calculate the earthwork. Subgrade superelevation and widening considered in the design calculations and design for the drainage protection. According to the traffic composition and trends combined with the local situation of road pavement structure building design, after comprehensive consideration on the full range of protection and drainage works to determine the structure and size, type, location, culvert along a preliminary structural design, and basic traffic safety facilities . Highway Engineering design considering the construction of a preliminary estimate, cost a total amount of 4,056,408 yuan.
　　　
Route calculated entire design flat, vertical and horizontal elements, the design of roadbed, road, small bridges and culverts, etc., thus the successful completion of Ganzhou, Jiangxi preliminary design of a new secondary road.

Key words: New secondary road; route design; roadbed design; pavement design; drainage design; Highway Engineering
