摘　　要：承台在结构中起着承上启下的重要作用,是保证上部结构的力有效传给基础的重要组成部分。在桥梁桩基、水池、海洋平台、储油罐等大型构筑物中,承台(或底板)的受力机理和传力模式越来越多地被研究人员所重视。本文主要从理论研究、试验研究、数值模拟分析等三个方面入手,对大型构筑物中的承台受力特性进行了综述,分析总结了国内不同构筑物中承台的研究概况,主要侧重于对承台的数值建模方法进行综述和比较,分析了不同模型的优缺点,最后提出了承台建模方面的一些问题和思考,为进一步的研究工作提供参考。Cap plays a transitional role in the structure. It is an irrtportant part to ensure the effective relatiorrship between the upper structure and the foundation. In the bridge 、water tank 、 ocean platforms 、 oil tank and other large- scale structures, the force mechanism and force mode about cap are more and more valued by researchers. The research method about large cap structure mainly includes theoretical research, experimental research, numerical simulation and other aspects. The domestic research status was summarized to lay special emphsis on the caps＇ numerical simulation methods and the advantages and disadvantages of different models. Finally, some questions were proposed for further research, which could provide references for engineering design and study.
