摘要

本设计为郑卢高速洛阳至洛宁段路基路面综合设计。本项目全线采用四车道高速公路标准进行设计，路基宽度26m，设计速度100km/h（起点至主线收费站1.7km为80km/h）。桥梁设计荷载等级公路-Ⅰ级；路基、桥涵洪水频率1/100、特大桥梁1/300；行车道宽度2×2×3.75m；桥梁全宽2×12.75m。其余指标根据中华人民共和国交通部颁发的《公路工程技术标准》（JTG B01－2003）及相关规范有关条文执行。

本设计包括路线的纵断面、横断面、边坡防护与加固、排水系统、涵洞、水泥混凝土路面设计、沥青混凝土路面设计。纵断面设计是根据道路等级、沿线自然条件和构造物控制标高等，确定路线合适的标高、各坡段的纵坡度和坡长，并设计竖曲线。横断面设计是根据设计资料说明，并参照“标准横断面图”，画出路幅宽度，填或挖的边坡线，在需要设置各种支挡工程和防护工程的地方画出该工程结构的断面示意图。边坡防护与加固设计是根据边坡的高度，路基横断面形式进行植草或圬工防护。排水系统设计是根据横断面沟底标高确定流水方向，并设置涵洞。路面设计是根据公路等级、交通量进行路面结构设计。施工组织设计是根据沿线路段自然条件和工程量来确定施工进度和布置施工总平面图。

关键词：高速公路、路基、路面、排水、防护

ABSTRACT

ABSTRACT：This design for Zheng-Lu highway Luoyang to Luoning section roadbed and pavement comprehensive design. The whole line of this project is designed according to the standard of four-lane expressway, the width of roadbed is 26m, the design speed is 100km/h (starting point to main line toll station 1.7km is 80km/h). Bridge design load grade highway-Ⅰ; roadbed, bridge and culvert flood frequency 1? 100, extra-large bridge 1? 300; carriageway width 2 × 2 × 3.75m; bridge full width 2 × 12.75m. The remaining indicators are in accordance with the Technical Standard for Highway Engineering issued by the Ministry of Communications of the people's Republic of China (JTG B01 / 2003) and other related indicators. Regulate the implementation of the relevant provisions.

The design includ the vertical section cross-sectional of the line design, slope protection and reinforcement, drainage systems, the culvert road design and the construction organization design . The profile design is based on grade of the road, the natural conditions and structures control elevation to determine the appropriate elevation of the road, the different slope of the vertical slope and the slope length and design of vertical curve. The main content of cross-sectional design is based on design information, in the light of the "standard cross-sectional map", drawing a way width, filling or digging slope of the slope, the need to set all kinds of support Engineering and protection engineering block where to draw the project structure of the cross-section diagram. Slope protection and reinforcement design is based on the height of the slope, cross-sectional form of grass embankment or masonry protection. Drainage system design is based on cross-sectional elevation of the ditch to determine the direction of flow, and set the culvert. Cement concrete pavement design is based on road grade, traffic volume pavement structure design. Construction design is based on the natural conditions along the roads and the construction quantities to determine the layout of the construction progress and the overall plan.
