本文系对苏联学者石氏关於彈性地基梁之理論作了适当的补充。石氏选悬臂梁作为彈性地基梁之輔助結構,本文則选二端附有悬臂之簡支梁。如是,寻求梁与地基之間的反力时,共用於建立法方程的工作,大致与石氏同,而用於求解該項方程的时間,則可大为縮短。 This article is an appropriate supplement to the theory of the Soviet scholar Shi Shiliang on the elastic foundation beam. As the auxiliary structure of the beam on the elastic foundation, the Ishikawa-selected cantilever beam is selected as the simple-supported beam with the cantilever at the two ends. If so, when seeking the reaction force between the beam and the foundation, the total work for establishing the normal equation is roughly the same as that of Shishi, and the time for solving the equation can be greatly shortened.
