摘要
基于邓肯E—B材料本构模型,本文建立了积石峡混凝土面板堆石坝的有限元计算模型,并运用中点增量法,进行了施工期和蓄水期的应力变形非线性有限元分析,获得了不同时期坝体、面板应力变形的分布与变化规律。通过有限元分析与计算,可以看出积石峡面板堆石坝是安全、可靠的。
Based on the Dengken E-B constitutive material model, the finite element calculating model for Jishxia CFRD was established using the middle point incremental. The non-linear finite element analysis for the stress-deformation of this dam has been carred out in contruction period and water store period, and has obtained the stress-strain distribution and variety rule at the dam and the face slab in different period. It was belived that the Jishixia CFRD was safe and reliable by finite element analysis and calculation.
