【Abstract】 the optimization design of the const ruction site transportation scheme can be summed up as the following: the least expenditure and the largest flow capacity can be achieved by designing transport ation route according to the requirement of construction period or testing and v erifying the traffic capacity of the established route, and calculating the key sections which can influence the raising of the flow capacity within the whole r oute. Practical matter can be abstracted as directional network by applying the mathematical tool-the diagram theory, so as to establish a mathematical model w hich is strict in theory, directly visual and clear in the steps of problem solv ing. This method has a universal significance for Irrigation works, highway, wat er route and other transportation systems.更多还原
