摘　　要：横断面设计主要内容是路拱曲线形式的选择和横坡度的确定,通过合理选用路拱形式和横坡度,能够方便雨水的排出,降低道路积水对行车的危害,减少积水对道路结构的损害。通过计算不同宽度的道路,在满足△中≥0.3%和1%≤△边≤2.5%的条件下,可以选择的路拱形式和路拱横坡。The main content of cross-section design is the selection of camber form and the determination of transverse slope.Through the reasonable selection of camber form and transverse slope,it is convenient to drain rainwater,reduce the harm of road ponding to driving and reduce the damage of ponding to road structure By calculating the requirements of△中≥0.3% and 1%≤△边≤2.5% with different width of new municipal road,which camber form and transverse slope can be selected.
