浏阳至花垣高速公路设计
摘要
本设计参照有关资料对浏阳至花垣高速公路K31+000——K39+。,为双向四车道,路基宽度:,中间带宽度:(含路缘带),行车道宽度:2××2m,硬路肩宽度:,土路肩宽度:,路缘带宽度:,。设计车速为100km/h。
本设计主要进行了平面定线,其中圆曲线半径最小为700m,最大为1600m,缓和曲线最短160m,最长为220m。%,%,最大坡长1640m,最短坡长520m。还有路基路面、排水系统以及土石方调运等方面的设计。其中排水系统包括矩形边沟、梯形排水沟,,。
沿线经过山区地形较复杂因此布设了2座高架桥,3座隧道及1座立交桥,还包括33个涵洞,还进行了挡土墙的布设。
关键词:浏花高速,路线设计,路基,路面。
ABSTRACT
This design reference to the relevant information of liuyang to spend through the highway K31 + 000 - K39 + paragraphs to carry on the design. Design route all m for four lanes, roadbed width: m, middle belt width: m (including side strip), driveway width: 2 * * 2 m, the hard shoulder width: m, dirt road shoulder width: m, width of the side strip: intermediate curb bandwidth of , the edge curb bandwidth of m. A design speed of 100 km/h.
This design mainly has carried on the plane alignment, the minimum radius of circular curve is 700 m, 1600 m, the maximum shortest easement curve 160 m, up to 220 m. Profile design maximum gradient of %, minimum slope of %, most slopes 1640 m long, the shortest slope 520 m long. And subgrade pavement, drainage system design and earthwork allocation and so on. Drainage system including rectangular ditches, trapezoidal ditch, were set to the depth of m, m wide.
Along through mountainous plex thus deployed two viaducts, three tunnels and overpasses, 1 included 33 culverts, also has carried on the retaining wall layout.
Keywords: LIUHUA highway, route design, roadbed, road surface.
