摘要
筏板基础是高层建筑结构的常见基础形式,在现有结构分析软件中没有考虑上部结构和地基的共同作用分析,导致设计结果偏于保守。本文在有限元技术发展的基础上,利用自由度耦合技术建立一考虑上下部结构共同作用的有限元分析模型,并通过变换筏板基础厚度、上部结构刚度和地基弹性模量等来分析筏板基础的内力变化和沉降量变化规律,这些共同作用机理的结论有助于同类工程问题的解决。
Raft foundation is a common basic structure form of high-rise building. The existing structural analysis software makes the results too conservative without considering the interaction between the superstructure and the foundation. This paper analyzes the raft foundation internal force change and settlement variation based on the development of the finite element technology,using the degree of freedom coupling technology to consider the upper and lower structure interaction finite element analysis model,by setting the foundation modulus of elasticity,raft foundation thickness,and stiffness of the upper structure. The conclusions of these common mechanisms of action are helpful to solve the problems in similar projects.
