【摘要】 有限元模型的单元网格剖分是影响分析精度的一个基本因素,是有限元分析前处理的主要工作。模型的不同形式单元网格剖分得到的计算结果也有所不同,理论上单元尺寸越小得到的计算结果精度越高。但针对具体结构,单元格的加密并不能带来理想的结果。该文由GID个人前/后处理软件7.0版对某水库大坝进行有限元动力分析,对大坝不同的单元网格剖分的地震反应结果进行了分析比较,这将对土石坝的有限元分析的单元格剖分类型的选择提供参考。更多还原

【Abstract】 The finite element model of the unit mesh accuracy of impact analysis are an essential element,it is the finite element analysis of the main tasks before the treatment.Model of different forms of unit mesh of the calculation results ob-tained are also different,in theory,the smaller the cell size obtained higher accuracy of calculation results.However,spe-cific structure,the cell is encrypted and can not bring about the desired results.This article from personal GID pre / post-processing software version 7.0 of a dam for finite element dynamic analysis of dam different unit mesh of the seismic re-sponse results were analyzed and compared,and this will of the finite element analysis of embankment dams dividing cell types of choice to provide some reference.更多还原
