堆石体流变参数反馈分析及应用

Back Analysis and Application of Creep Parameters for Rockfill

针对高面板堆石坝的流变问题进行分析,利用有限元结合神经网络技术对堆石体的流变参数进行反馈分析。结合工程实践,验证了分析方法的合理性和可靠性,同时也揭示了高面板堆石坝堆石体的流变规律。

This paper analyzes the rheologic problem of high facing concrete rockfill dam and uses the finite element combining with nervous network technology to conduct feedback analysis on the rheologic parameters of rockfill body. In combination with the project practice, the reasonability and reliability of such method have been proved and the rheologic laws of the rockfill body of high concrete facing rockfill dam has been revealed.
