1、摘要拱壩是一種重要的壩型，以結(jié)構(gòu)合理和體形優(yōu)美而著稱，近年來，拱壩越來越受到大壩設(shè)計(jì)者們的重視，其應(yīng)用也越來越廣泛。本文基于ANSYS參數(shù)化設(shè)計(jì)語言APDL對三次樣條線型拱壩的體形優(yōu)化設(shè)計(jì)進(jìn)行了研究，主要內(nèi)容如下：1．簡要介紹了拱壩建設(shè)發(fā)展概況，從拱壩幾何模型、優(yōu)化設(shè)計(jì)模型及優(yōu)化方法三個(gè)方面概述了拱壩體形優(yōu)化設(shè)計(jì)的研究進(jìn)展。2．介紹了三次樣條插值函數(shù)的基本理論和方法，給出了三次樣條線型拱壩體形的構(gòu)造方法，并建立了三次樣條線型拱壩體形優(yōu)化設(shè)計(jì)‘?dāng)?shù)學(xué)模型。3．論述了拱壩結(jié)構(gòu)有限元分析基本理論和有限元等效應(yīng)力計(jì)算方法，提出了基于APD
2、L的拱壩建模與結(jié)構(gòu)分析方法，最后對白鶴灘拱壩進(jìn)行了結(jié)構(gòu)分析，得出比較合理的結(jié)果。4．論述了遺傳算法的基本理論與方法，提出了一種加速微種群遺傳算法，并給出了相應(yīng)的計(jì)算步驟和優(yōu)化算例。5．對白鶴灘拱壩進(jìn)行了單目標(biāo)及多目標(biāo)的體形優(yōu)化設(shè)計(jì)研究，提出了拱壩體形多目標(biāo)優(yōu)化的博弈方法，編制了相應(yīng)的優(yōu)化程序。6．最后，本文對有待于進(jìn)一步研究的問題進(jìn)行了討論。關(guān)鍵詞：拱壩體形優(yōu)化三次樣條插值函數(shù)APDL加速微種群遺傳算法博弈論ABSTRACTArchdamisaveryimportantdamstyle，itisfamousofreasonabl
