The Shape Optimization Design Of Double Arch Dam Based On The Finite Element Method

The shape optimization design of arch dam is using mathematics plan method to look for the most rational bodily form under the given topography, geology and load. The foreign countries research on this respect started in the latter stage of the sixties of 20 century, our country started from the latter stage of the seventies, the key research is arch dam optimize design method based on arched girder divided load method, through 20 years efforts on this, our country's theoretical research on the optimization design of arch dam is in first place in the world. With the deepening studying, the shortcoming of arched girder divided load method is more obvious, in order to solve its insufficiently, many domestic and international scholars do much work in the optimization design of arch dam, including various calculation procedures edited with finite element method to ameliorating the optimization calculation method, but most are more difficult to apply to the actual project. The purpose of this text's studies is to enrich, improve the optimize design system of arch dam, reduce the frequent and complicated work of optimization design of arch dam, realize the intelligent automation of the computer, enable to shorten the cycle of the optimization design of arch dam, improve design quality and level, thus make the prominent economic benefit and social benefit.The concrete double arch dam optimization design made in this text direct aim at project application study, That is given the definite linetype of arch dam to process optimization design through adjusting the design variables, using the finite element method to calculate the mechanical characteristic of arch dam, solving the full-automatically calculate the problem of different parameters of arch dam, improving the efficiency of optimization design of arch dam at the same time.Firstly, on the basis of consulting different arch dams optimization models established by the scholars in the domestic and overseas, through careful analyze and study the shape of arch dam and its mechanical characteristic, the optimize design model of arch dam was established as a linear programming model, and on the basis of this linear model and the coordinate systems constituted, analyze the stability of dam body, the optimization center angle, the need...
