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。 The different design methods of flat raft are reviewed. By means of establishing the plane stress model in the middle of the upper plate, the force characteristics of flat raft with same thickness and flat raft with upper / lower column cap are distinguished. According to the proposed cap on the lower column cap plate raft in the calculation should take different calculations. Taking an engineering raft foundation as an example, it shows that using the proposed method in this paper can improve the accuracy and economy of raft design.
