Abstract: Trial and error method or diagrammatic method was used to anti-press design of dike and dam. The former was very heavy in working load, the latter was miscellaneous in chart and table, and thus led to restrict the precision. Aiming at the localization, and taking advantages of high parallel, random and adaptive searching of genetic algorithm(GA), the model of optimizin g anti-press design based on GA is established. Without direct relation to parameters, an outcome group of the model is controlled in seeking result, thus the method not only is high in searching efficiency, but also can avoid running into local extremum. The study through an illustration shows that the model is high in precision. Thus a new arithmetic is put forward for optimizing anti-press design of dike and dam.
