This design according to the data that given,by the analysis of the orginally data, according to natural characteristics, in orginally of road segant、hydrology geograph...etc. According to 《Technical Standard of Highway Engineering》etc. Ministry of Transportation & Communications distributing index sign, complete the design.During the design totally manage the lasted technical standard and general coad.Complete follow design. First, basis of the starting point and terminal point that given, select suitable control point and judging by the separation of two isohypsea and average grade,then preliminary define practicable plan of the route.Through reviseing determine the plan alignment fixed 《Technical Standard of Highway Engineering》JTG B01-2003.Second, judging by maximum longitudinal grade、limitde line of grade、grade compensation baded on 《General Code for Design of Route》ect,takes into elevation of economic point and point of minor control, define profile grade line .Third, take into degree of highway and volume of traffic, define the type of pavement and complete pavement design. Fourth, define culvert's diameter basis of water collecting area that reckoned. Define position of bridge and culverts and allocate culverts.Take avoiding traffic block and reducing traffic accident as design criteria.Do the Intersection grade design.Last ,in the help of associate professor Song feng li, draw with computer skilly and do approximate calculation with WCOST2002.
