Abstract

The design and the choice of the diversion system of a dam depends on topographic conditions, the kind of constructing area (from the point of geology and geotechnical), the river hydraulic situation, forecasted expenses and etc. One of the fashionable kinds of these systems is use of a cofferdam with one or few tunnels. According to the designing instructions and the researchers’ viewpoint, the selection of the diversion system dimensions must be done exactly select that it can pass flood (with maximum discharge) with a fixed return cycle and safely from itself. Choosing the best dimensions of a temporary diversion system from the economical and technical viewpoints, need to make use of optimization methods. The plan of good diverting system is plan that with the least cost, minimize the serious danger and the probable flood in the working lot, while being built. In this paper, by describing the method of calculating the costs of constructing the diversion system which includes the cost of diversion tunnel excavation, embankment and erection UPSTREAM AND DOWNSTREAM COFFERDAM, maintaining and lining of diversion tunnel a new method for calculating the minimum cost of constructing the diversion system, by satisfying all designing concerns is presented. For performing the optimization, the LAGRANGE MULTIPLIER OPTIMIZATION METHOD has been used. Its results will become compared with the real dam. The results showed that the Lagrange multiplier method and genetic algorithm to optimize the cost of construction Anjraf as well as to optimize the extraction of minimal diameter diversion tunnel construction tunnel and reduce the time of neural network will be better.
