有限元数值分析在高层建筑逆作法中的应用探讨

Discussion of Finite Element Numerical Analysis Application in the High-Rise Building Uni-Axial

随着我国城市经济转型的不断深入,城市文明程度相应得到了提高,与此同时,建筑施工技术得到迅速发展,对高层建筑中深基坑开挖技术的要求也越来越高。在深基坑开挖的技术中,逆作法作为新兴技术在深基坑支护方面有着较强的适用性[1]。有限元分析法作为有效的数值分析方法逐渐受到了建筑专家和学者的重视。本文对有限元分析在逆作法中的应用进行了分析,从逆作法施工的发展及特点入手,对逆作法存在的问题进行了描述,进而对逆作法有限元分析过程进行了探究,具有较强的指导意义。

With the deepening of the urban economic transformation in China,the urban civilization degree is improved,at the same time,construction technology is developing rapidly,demand for deep foundation pit excavation technology of a high-rise building is becoming more and more high. As for the technologies in deep foundation pit excavation,uni-axial as an emerging technology has strong applicability in deep foundation pit supporting[1].Finite element analysis method as an effective numerical analysis method has been gradually received attention from building experts and scholars. In this paper,the finite element analysis application in the uni-axial is analyzed,the existing problems of uni-axial are described from the development and the characteristics of the uni-axial,and then the uniaxial finite element analysis process is explored,which has great guiding significance.
