摘要

在前人工作的基础上

从宏观上建立了一个用于面板坝流变分析的堆石流变模型: 堆石的瞬时弹塑性变形由椭圆-抛物双屈服面模型确定

并计入时间效应

由双曲线函数经验公式计算堆石与时间有关的粘塑性变形。通过现场实测结果的反分析验证了模型的可靠性。

Abstract

Based on previous researchers

this paper establishes a rheology model of rockfill used in the rheology analysis of concrete face rockfill dam despiting the rockfill microstructure. In this model

the instantaneous elasto-plastic deformations of rock fills are computed by the oblong-parabola two yield surface model

and considering the time effects

the time dependent visco-plastic deformations are derived from the empirical equation of hyperbolic function .The reliability of this rheology model isproved to be good after perfo rming inverse problems with deformation records in-situ .
