一、概述 弹性地基梁在水运工程中已得到广泛应用,有如码头或仓库的起重机轨道梁等。由于梁的各段间存在相对沉降,一般将梁各段之间做成铰接,使之在铰接处挠度连续而转角不连续,以达到减小梁的内力和地基反力。这种分段铰接的无限长连续梁简称为铰接梁。 本文在分析弹性地基上的铰接梁时采用了文克尔假定并导出了以矩阵表示的地基单 First, an overview of the elastic foundation beam in water projects have been widely used, such as the terminal or warehouse crane track beam. Due to the relative settlement between beams, the beams are generally hinged between the segments so that the joints are continuously deflected and the corners are not continuous, so as to reduce the internal force of the beams and the reaction force of the foundation. This staged articulated endless continuous beam is simply called an articulated beam. In this paper, we use the Weckel’s assumption in the analysis of articulated beams on elastic foundations and derive a single foundation
