摘　　要：针对装配式柱下独立基础进行讨论,总结归纳装配式柱下独立基础的现有结构形式与结构特点,给出一种较为新型的装配式柱下独立基础形式,提高独立基础的整体施工效率与预制率,同时利用有限元软件结合实际工程,建立一个上部结构与独立基础相互协调变形的数值模型,主要研究该模型建立过程中的各个重要组成节点,对于柱下独立基础进行有效的建模解析,将建模过程一一细化,合理化的建模流程也能够进一步保障数值建模的有效性,为后期准确分析在上部荷载作用下柱下独立基础的变形特征与内力变化规律提供强有力保障。For prefabricated independent foundation under column is discussed,sums up the existing structure of fabricated under column independent foundation form and structure characteristics,are a relatively new type of prefabricated independent foundation under column form,improve the efficiency of the overall construction of independent foundation and prefabricated rate,at the same time by using the finite element software,combined with the actual project to establish a upper structure and foundation of independent coordination deformation numerical model Type,the main research each important component in the process of the node,the model for independent foundation under column for effective analytical modeling,the modeling process to refine,rationalization of the modeling process will also be able to further guarantee the validity of the numerical modeling,late for accurate analysis of independent foundation under column under the upper load characteristics of deformation and internal force variation law provide strong guarantee.
