框架高层结构与筏板基础的施工研究与应用

Research and Application of Frame High Rise Structure and Raft Foundation Construction

为了在高层建筑设计中确保结构设计安全性且降低建设成本,基于数值模拟提出了高层框架-桩筏基础的分析方法。首先,分析了高层框架结构荷载与桩土接触方式;其次,采用有限元软件ABAQUS分别建立考虑共同作用的模型和不考虑共同作用的模型,分析结果并说明共同作用模型的合理性;最后,以现代产业区蓝白领公寓工程为研究对象,说明本文方法的分析过程。结果表明:所采用的方法可以得到该建筑合理的受力情况与所需数据,计算结果可作为该类建筑的设计依据。

In order to ensure structure safety and reduce construction cost in the design of high-rise buildings,this paper analyzed the method of high rise frame-piled raft foundation based on numerical simulation.Firstly,the load of high-rise frame structure and the method of pile-soil contact are analyzed,and then,finite element software ABAQUS is used to build the model considering interaction.By analyzing the results,the rationality of the interaction model is explained.Finally,the analysis process of the method is illustrated by research object of a frame-piled raft foundation high-rise building.The results show that this method can get a reasonable force status of the building and the required data and calculation results can be used as design basis of this kind of building.
