【摘要】 本文应用有限层方法,选择Bessel级数为位移函数,对弹性地基上受轴对称荷载作用的圆形厚板进行了力学分析。本文考虑了圆板周边固定、简支、自由等三种边界条件,并分别研究了Winkler地基和弹性半空间体地基上的圆形厚板。文中提供了算例,并在室内做了有机玻璃模型试验。结果表明,本文计算方法具有收敛速度快、计算精度高、占用计算机内存少等优点。更多还原

【Abstract】 In this paper axisymmetric thick circular Plates resting on elastic foundation are analysed by the finite layer method. Bessel series is chosen as a displacement function Boundary conditions are considered of clamped, simple-supported and free edge at Plate circumference. The lates b aoed on Winkler foundation and elastic half sPaCe foundation are studied. Computation examples also are given. The experiment is made with Plexiglass Plate in laboratory. Results show that the computing method in this PaPer has advantages of high convergence rate, goodaccuracy and occupying less computer memory.更多还原
