摘要
将双联两铰拱涵的墩台与拱顶视为一整体结构,考虑墩台与顶拱的协同效应,在文克尔假设基础上,根据力法原理提出了双联两铰拱涵整体结构内力计算的新方法。实例计算表明,本方法不仅揭示了拱顶破坏的机理,且使拱顶设计合理,墩台体积明显减小。
Regarding the double hole two hinged arch culvert pier and top arch as a massive structure,considering the synergetic effect and elastic formation of pier and top arch and based on Winkers Hypothesis,the paper puts forward the hypogene calculation of double hole two hinged arch culverts massive structure according to the principle of force method.The example and calculation show that the method in this paper not only reveals the arch fracfure mechanism but also a indicates reasonable design of arch crown and a smaller volume of pier.
