【摘要】 通过用邓肯~张E~B模型,对岗曲河面板堆石坝在竣工期、蓄水期和泄水期进行了非线性有限元仿真计算,特别考虑了坝上溢洪道在泄水期,泄水水流对坝体应力和变形的影响,研究了大坝在三种工况下的应力变形特点及分布规律。计算结果分析表明,坝体竣工期、蓄水期的应力应变符合一般规律,泄水期的应力与竣工期、蓄水期相比有所减小,变形相差不是很大。更多还原

【Abstract】 Stress and deformation of Gangquhe CFRD was calculated with the nonlinear finite element method based on the Duncan-Chang E~B model in the completion storage and discharging periods.The results indicate that stress and deformation of the dam in the discharging period is not larger than another.更多还原
