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。
The cap plays an important role in the structure and is an important part of ensuring that the force of the superstructure is effectively transmitted to the foundation. In the bridge pile foundation, pool, offshore platform, oil tank and other large structures, the bearing platform (or floor) of the force mechanism and force transmission mode more and more researchers attention. This article mainly from the theoretical research, experimental research, numerical simulation analysis of three aspects, carried out in large-scale structures in the bearing capacity of the platform were summarized, analyzed and summarized the different structures of the cap platform research, mainly focused on the bearing The methods of numerical modeling are summarized and compared, the advantages and disadvantages of different models are analyzed, and some problems and reflections on the modeling of caps are put forward in the end to provide references for further research.
