ABAQUS在水电站厂房地基应力分析中的应用

Application of ABAQUS in Foundation Stress Analysis of Hydropower Station Plant

ABAQUS软件是目前国际上先进的大型通用非线性有限元分析软件,在工程领域得到了广泛的应用,对岩土工程中的实际模型所取的各种边界条件以及土体的非线性本构关系有着很好的适应性。文章利用ABAQUS软件建立了三维有限元模型,对龙溪口水电站厂房的机组段和安装间段的地基应力进行了分析,为龙溪口水电站厂房的稳定设计提供了技术支撑,对同类水电站厂房的设计和施工具有参考意义。

ABAQUS software belongs to international advanced large-scale general nonlinear finite element analysis software,which has been widely used in the engineering field.It has a good adaptability to various boundary conditions and nonlinear constitutive relations of soil mass obtained from practical models in geotechnical engineering.ABAQUS software is used for setting up a three-dimensional finite element modelin the paper,and the foundation stress of the unit section and assembly bay of Longxikou Hydropower Station Plant is analyzed,which provides technical support for the stability design of Longxikou Hydropower Station.It has reference significance for the design and construction of similar hydropower stations.
