[摘要] 回顾了平板式筏板的不同设计方法，通过建立柱上板带中部的平面应力模型，区分了等厚平板式筏板及上/下柱帽平板式筏板的受力特点，并以此为依据提出上柱帽与下柱帽平板式筏板在计算中应采取不同的计算方法。以某工程筏板基础为例，说明采用本文建议方法计算有助于提高筏板设计的精度和经济性。

Abstract: Several methods of flat plate rooting design were reviewed. By analyzing a plane stress model with FEM through straight line between two columns, different mechanical characteristics between flat plate rooting with equal thickness and flat plate rooting with up or down column-capital were compared. Thus, it was raised as a point of view that different methods of calculation should be taken in calculating flat plate rooting with up or down column-capital. Taking a flat plate rooting design in a project for example, the accuracy and economy can be enhanced by applying the advised proposals.

Keywords: flat plate rooting; column-capital; FEM
