青铜峡大坝电站坝段变形性态及裂缝物理成因分析

摘要

在青铜峡大坝电站5号坝段原型观测资料分析基础上，应用三维有限元方法对坝体结构进行分析计算，采用多种监控模型和分析方法，综合考虑多种影响因素，对裂缝成因进行分析。并对大坝进行了综合分析和安全评价，为大坝安全监控提供了依据。%The data observed during the operation of No. 5 block ofQingtongxia Powerhouse are analyzed. The block is analyzed by means of the three dimensional finite element method. Considering the effects of several factors, a genetic analysis of cracks in the block is done with several monitoring models. The results from the models provide a basis for comprehensive analysis and safety evaluation of the large dam and for the monitoring of dam safety.
