Stress and Deformation Analysis of Lasuluo Face Rockfill Dam based on E-B Model

面板堆石坝具有诸多优点,在高坝建设中得到广泛应用。基于土石料的E-B本构模型,采用有限元法分析了拉苏洛面板堆石坝在静力条件下的应力变形特性,计算结果符合面板堆石坝的普遍规律,且变形量满足规范要求,表明坝体拟选筑坝材料合理可靠。

Face rockfill dam has many advantages and has been widely used in high dam construction.Based on the E-B constitutive model of earth-stone materials,this paper analyzes the stress and deformation characteristics of Lasuluo face rockfill dam under static force by applying the finite element method.The calculation results accord with the general law of face rockfill dam,and the deformation meets the specification requirements,which indicates that the proposed dam material is reasonable and reliable.
