|
摘要
【目的】建立新的有限元分析方法,为准确合理地进行高面板堆石坝的坝坡稳定动力分析提供参考。【方法】基于应力水平的有限元计算结果,将大型有限元软件ADINA的应力变形计算功能与GEO-SLOPE软件的边坡稳定分析功能相结合,提出了高面板堆石坝坝坡稳定动力有限元分析方法,并利用该方法对紫坪铺水利枢纽工程面板堆石坝在"5.12"汶川大地震期间的大坝动力反应及坝坡稳定进行了三维有限元模拟分析。【结果】利用建立的高面板堆石坝坝坡稳定动力有限元分析方法,对紫坪铺水利枢纽工程面板堆石坝位移的动力分析计算结果与该坝震后位移实际观测结果基本吻合,坝坡动力稳定的分析计算结果与震后实际调查分析结果基本一致。【结论】所提出的高面板堆石坝坝坡稳定动力有限元分析方法是合理的,所获得的计算结果准确可信。
【Objective】 The study is to establish a new finite element analysis method and to provide references for an accurate and reasonable dynamic analysis of slope stability of high-CFRD.【Method】 This paper presents a high CFRD dam slope stability analysis method of dynamic finite element based on the results of finite element stress level,by combining the calculation features of stress and deformation of large-scale finite element software ADINA with the slope stability analysis of the software GEO-SLOPE.Based on the method,this article creates a three-dimensional finite element model of Zipingpu CFRD water control project to analyse the dynamic response and slope stability of the dam in the period of '5·12' Wenchuan earthquake.【Result】 Using the established high CFRD dam slope stability analysis method of dynamic finite element,the dynamic calculation results of the dam displacement of Zipingpu water control project CFRD are consistent with the observation results after the earthquake.The analytical results of dynamic stability on the slope of dam are also consistent with the actual investigation results after the earthquake.【Conclusion】 The results proves that the presented high CFRD dam slope stability analysis method of dynamic finite element is reasonable and the obtained analysis results are accurate.
