超高心墙堆石坝大型振动台模型试验及数值模拟
Large-scale shaking table test and numerical analysis of super high core rock-fill dam
摘要
Abstract
Anti-seismic design for high dam construction in southwest China is a crucial issue.Shaking table test is an effective tool in studies of dynamic response and earthquake damage mechanism and also for verification of dynamic analysis methods.This paper presents the design and measurements of shaking table tests for the Shuangjiangkou super-high core rock-fill dam and an equivalent linear method for simulation of the model dam＇s dynamic response with a comparison of the measured and simulated data.Results of both methods show the most dangerous position on the dam＇s downstream surface of 0.75~0.85H and the dam＇s weaker dynamic responses in the full storage case,while FEM that is not accurate enough to simulate large deformation on incompact slope,produces lower values than the measurements.As a non-linear visco-elastic model,the equivalent linear method can not simulate pre-vibration case or failure process of a dam.关键词
