xx高速公路施工圖設(shè)計(jì)

摘 要
本設(shè)計(jì)為雙向四車道，設(shè)計(jì)行車時(shí)速100公里，路線全長(zhǎng)為2720.231m，路基寬度為26m，行車道寬度為4×3.75m，其中規(guī)劃遠(yuǎn)景設(shè)計(jì)年限為20年。設(shè)計(jì)內(nèi)容包括道路技術(shù)等級(jí)與技術(shù)標(biāo)準(zhǔn)論證、道路方案設(shè)計(jì)、指定路段技術(shù)設(shè)計(jì)等。
選線與定線是根據(jù)交通量確定道路等級(jí)，在地形圖上確定三條備選路線，通過三個(gè)方案主要指標(biāo)進(jìn)行比選，確定最優(yōu)方案。平面設(shè)計(jì)按照書中要求選定路線的各種技術(shù)指標(biāo)，計(jì)算平曲線參數(shù)，確定線形。縱斷面設(shè)計(jì)主要考慮縱坡在滿足書中和規(guī)范上各規(guī)定的情況下，盡量使填挖趨于平衡，利于排水和行車舒適，計(jì)算豎曲線要素。橫斷面設(shè)計(jì)中考慮排水和行車安全穩(wěn)定等因素確定道路的橫斷面形式。路基設(shè)計(jì)主要進(jìn)行確定壓實(shí)標(biāo)準(zhǔn)、路基高度、邊坡形狀、坡度、路基排水等設(shè)計(jì)。公路邊坡防護(hù)采用合理設(shè)計(jì)坡比，設(shè)置漿砌片石護(hù)面墻、噴漿護(hù)坡、擋土墻等進(jìn)行加固，水土流失防治效果較好。公路沿線設(shè)置了完善的排水系統(tǒng)，如邊溝、排水溝、截水溝等，將地表徑流引入自然溪溝或通過涵洞排出。路面采用瀝青路面設(shè)計(jì)，三層體系。
本設(shè)計(jì)使用了緯地道路設(shè)計(jì)軟件出圖，效率高，避免了人力資源的浪費(fèi)。

Abstract
This design is four-lane two-way , design traffic speed of 100 km, the road length 2720.231m, sub grade width of 26m, the carriageway width of 4 × 3.75m, among them plan to design service life as 20 years in distant view. Design the content and include the industrial grade of the road and proof, road conceptual design, appointing the technical design of highway section and special topic to be designed of the technical standard.

Route selection and alignment determined in accordance with the road traffic levels, the topographic map to determine the three alternative routes, through three main indicators of the program than the election, determine the best option. Graphic design requirements in accordance with the selected book line of technical indicators, calculate flat curve parameters, determine the linear; Profile Design major consideration longitudinal and specification to meet the provisions of the book where, as far as possible so that tends to balance cut and fill, drainage and road comfort conducive to calculate vertical curve elements. Cross-sectional design of the drainage and road security and stability into account such factors determine the form of road cross-section. Foundation primarily designed to determine the compaction standards, embankment height, slope shape, slope, embankment and drainage design. Highway Slope Protection reasonable than the slope design, made of mortar and stones set retaining wall, spray Pitching and reinforce retaining walls, Control soil erosion better. The road has along the route established the perfect drainage system, like side ditches, drains, ditches closed, and so on，to the introduction of surface runoff or through natural Gully discharge culvert. Pavement used asphalt pavement design, the three-tier system.
This design used Hint road design software to leave the chart, high efficiency, avoiding the waste of human resources
Keywords: Asphalt Pavement; Line; Cross section; Vertical section; Retaining walls.
