双江口心墙堆石坝三维动力分析及模型试验验证
3D dynamic analysis and shaking table tests verification of Shuangjiangkou core rock-fill dam
摘要
Abstract
This paper presents a shaking table test and model dam analysis by equivalent linear method for the highest core rock-fill dam in the world, the Shuangjiangkou dam, including vertical profiles of acceleration amplification factor and its variations along dam axis and in stream direction. The results show that the equivalent linear method is applicable to dynamic analysis of rock-fill dam, but its calculation error is quite obvious, because computed values smaller than the tested values could occur if FEM meets difficulties in accurate simulation of large deformation on incompaet slope. This error becomes greater for stronger seismic inputs. The natural frequency of prototype dam estimated by similarity theory is close to the calculations. This work demonstrates that shaking table test provides important reference to study of dynamic characteristics of high rock-fill dam.关键词
