| 摘 要： | 进行了双参数地基板的有限元分析,基于Mindlin-Reissner中厚板理论给出了双参数地基上广义协调厚薄板通用元的计算公式,并利用位移反分析和遗传算法进行了地基参数识别。有限元计算与试验实测结果吻合良好。为便于比较,文中还给出了Winkler地基和半空间地基的计算结果。

| Abstract: | Finite element analysis of slabs on double-parameter foundation is presented in this paper. Based on Mindlin-Reissner plate theory, a generalized conforming element for thick-thin slab on foundation is formulated. Inverse analysis of deflection and genetic algorithm are used to identify the foundation parameter. The numerical results of FEM are in good agreement with the experimental results. For comparison, the results for Winkler and Subspace foundation are also given. |
