ABSTRACT The preliminary design of freeway in Yunnan Province [Abstract]: This design is the highway preliminary design, it mainly includes theroute, the roadbed and the draining water design, the road surface and the draining water design as well as the bridge culvert design. Firstinitially draws up the route plan in the surface contour map, decideson the wire and the determination linear target, in the computationthe pile coordinates, draws up the even tune chart; vertical section thedesign, rests on each center pile elevation repeatedly to try theslope, the plan profile diagram. When design must pay attention to thevertical curve and plane curve matching. The roadbed cross sectiondesign, determines in the roadbed crosswise certain scope the groundelevation, the use standard template carries on the belt hat to thecross section, and according to the above carries on the cubic meterof earth and stone the computation. The draining water design carries on the design based on the drainingwater design standard and the correlation geology situation. Simultaneously carries on the pavement structure level the design, inthe pavement structure design including the asphalt concrete roadsurface, the cement concrete road surface two kind of pavementdesigns, the bituminous pavement design take the elastic layeredsystem theory as the fou
