农村田间道路典型结构设计.docVIP

PAGE PAGE 1 PAGE PAGE 1 摘要 本设计为青岛世园会天水路设计。天水路为城市主干道路，东至铜川路，西至达川路，全长约km，设计车速为km/h，道路形式为双幅路，双向六车道。 设计中道路平面设计根据总体布局规划，设置了两个平曲线，半径分别为和，均为大半径曲线，可不设缓和曲线，采用直线与圆曲线之间相连。纵断面设计以平曲线设计为依据，满足平纵线型组合要求，并且结合该路段地形条件，使其填挖平衡。设计采用两条竖曲线，半径分别为m和m。交叉口设计包括平面设计和立面设计，平面设计形式为拓宽路口式十字交叉口，进口道增设左右转车道，立面设计根据该斜坡地形的高程采用方格网法绘制立面图。道路的路基路面设计，根据道路等级及地形条件，并做好路基排水设计。路面进行分层设计，对各层设计指标进行验算。根据国家规范标准对道路给排水及管线设计，做好道路的绿化和照明。 关键词：城市道路；横断面设计；平面设计；纵断面设计；交叉口；排水 PAGE PAGE 2 PAGE PAGE 1 Abstract The name of this design for Qingdao International Horticultural Exposition is TianShui road,which is the main road of the city , east to TongChuan road, west to DaChuan road, total length is km, design speed is km/h and road form for double amplitude and six lanes. Road plane design set up two plane curve,big radius curves based on general layout,the radius of which are and respectively so that it is unnecessary to set up easement curve and connected with straight line and circular curve .profile design is based on plane curve design, which is satisfied the requirement of flat vertical linear combination and the balance of the fill to dig combined with the terrain conditions.The design use two vertical curves which radius areand respectively.Intersection design including the plane design and the facade design, plane design form is intersections in the form of widening the road, import way add left and right turn lanes, facade design use grid method to draw the elevation according to the slope of the terrain elevation .Road subgrade pavement design is based on road grade and terrain conditions,meanwhile, make the roadbed drainage design.Making road hierarchical design and checking design indexes calculation for each layer.Making road drainage and pipeline design and completing the road greening and lighting based on the national standards.
