拱坝的体型设计和应力分析是拱坝设计的主要内容之一。本文扼要地论述了东江拱坝体型设计;分析比较了有限单元法、拱梁分载法程序和计算与实验的成果。由此看出诸法程序算得的拱冠、拱座主应力沿坝高分布的趋势与规律是一致的;东江拱坝应力状况能满足设计要求。东江拱坝应力分析表明:在目前拱坝设计中,拱梁分载法可作为基本的应力分析方法,而其它方法作为校核。
Arch dam body design and stress analysis is one of the main contents of arch dam design. This article briefly discusses the body design of the Dongjiang arch dam; analyzes and compares the finite element method, the procedure of arch beam loading method and the results of calculation and experiment. From this, we can see that the trend and rule of the principal stress of arch crown and abutment along the dam height are consistent; the stress state of Dongjiang arch dam can meet the design requirements. The stress analysis of the Dongjiang arch dam shows that in the current arch dam design, the arch beam loading method can be used as the basic stress analysis method, while other methods as the check.
