摘要
给出了环形均匀荷载作用下刚性下卧层上中厚度地基的沉陷系数和圆板挠度计算公式,使得一般中厚度地基上圆板的计算简单易行。用链杆法求解中厚度地基上圆板,大大地减小了求解问题的规模,计算效率显著提高。文中算例说明,半空间地基和文克勒地基都是中厚度地基的特殊情况。
Analytical formulas to compute the settlement of elastic layer subjected to rectangutar uniform load are presented. The elastic layer has a finite depth and sticks to a rigid stratum. The Finite Element Method is used to find the displacement of plates, and the Rigid Bar Method is used to determine the contact pressure between plates and soil foundations. By virtue of the advantages of FEM and RBM the problems are simplified and the computational efficiency is improved remarkably. The numerical results prove that both half-space and winkler foundation are particular cases of the elastic layer of finite depth.
