摘 要

中央南街立交桥工程位于城市的骨架路网南广路与中央南街渤海大道交叉的中央节点位置，定位为枢纽型互通的立交桥，立交式为苜蓿叶加半定向匝道全互通式立交。其中灌注桩424根，承台127座，桥台12座，墩柱113根，箱梁37联。东西长980米，南北长814米，主线为双线的六车道。立交系统占地面积约235亩，路基段总面积57688平方米，桥梁段总面积38128.2平方米。中央南街立交桥东西方向，起点是西侧时代服装城，终点是东侧光彩市场3号厅东侧。南北方向，起点是女儿河桥南端，终点是南侧兰溪谷小区南门。2012年3月开工建设，立交桥东西主线已于2013年11月正式通车。

中央南街立交桥工程共包括供南外环路、中央南街(渤海大道)机动车辆沟通的立交系统以及供立交周边行人、非机动车沟通的人非辅道系统。人非辅道系统是为了方便立交周边地方行人、非机动车出入，同时能够满足小型机动车辆在各自象限内的通行需要。除工程内容主要的道路工程、桥梁工程外，相关的配套工程还包括交通工程、电气工程、临时工程、排水工程以及绿化工程等。

本设计全部设计图纸采用计算机辅助设计绘制，计算机编档、排版，打印出图及论文。

Abstract

Central Street overpass project is located in the city of skeleton network Nanguang road and Central South Bohai Road, cross the central node position and orientation for hub intercommunicating overpass and interchange for alfalfa leaf and semi directional ramp full Interchange Interchange. The pile cap 424, 127 seat, 12 seat pier abutment, 113, 37 combined box girder. Things 980 meters long, 814 meters north and south, the main line of the six lanes of the two lane. Interchange system covers an area of about 235 acres, the total area of 57688 square meters of subgrade section, the total area of 38128.2 square meters of bridge section. The Central Street overpass east-west direction, the starting point is on the west side of the era clothing city, east end is the glorious market hall No. 3 east. The north-south direction, the starting point is the southernmost end of the South Bridge daughter, Lanxi Valley District South gate. Started construction in March 2012, the main line of the overpass was officially opened to traffic in November 2013.

Central Street overpass project includes for South Outer Ring Road, the Central Street (Bohai Avenue) motor vehicle communication interchange system and for overpass peripheral pedestrians, non motor vehicle communication of non des Voeux Road system. The non auxiliary road system is designed to facilitate the access of pedestrians and non motor vehicles in the surrounding area, and to meet the needs of the small motor vehicles in their respective quadrant. In addition to the main contents of the road engineering, bridge engineering, the relevant supporting projects also include traffic engineering, electrical engineering, temporary works,drainage works and greening projects.

All design drawings of the design drawing using computer-aided design, computer archiving, publishing, print out the maps and papers.

1.1引言

中央南街立交桥立交式为苜蓿叶加半定向匝道全互通式立交。工程共包括供南外环路、中央南街(渤海大道)机动车辆沟通的立交系统和供立交周边行人、非机动车沟通的人非辅道系统。整个工程占地面积大约235亩。立交的系统整体形态为涡轮型，采用苜蓿叶半定向匝道型全互通式的立交形式。人非辅道系统是为了方便立交周边地方行人、非机动车出入，同时能够满足小型机动车辆在各自象限内通行的需要。除工程内容主要的道路工程、桥梁工程外，相关的配套工程还包括交通工程、电气工程、临时工程、排水工程以及绿化工程等。扩大城市规模、拓展城市空间、增强城市功能、推动城市向南发展等方面都有着重要意义。特别是作为2013年中国•锦州世界园林博览会和全运会的交通枢纽保障工程。
