摘要
本文根据钢纤维混凝土良好的塑性性质,以考虑横向剪切变形的MINDLIN板和弹塑性理论为基础,对WINKLER地基上路面板的极限承载力进行了弹塑性有限元分析和计算。给出了路面板板中、板边、板角部位极限破坏时的裂缝开裂状态(即塑性铰线)和极限承载力,并将有限元结果和塑性铰线理论结果进行比较和分析。
In this paper, according to the better plasticity quality of steel fibre concrete,based on MINDLIN plate considering the effect of transverse shear deformation and elastic-plastic theory, the ultimate bearing capacities of concrete pavements on an elastic subgrade are computed. The results of ultimate crack states and ultimate bearing capacities for central, edge, corner loadings are presented. The results are analyzed by the comparison of plastic hinge line theory.
