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 。The data observed during the operation of No. 5 block of Qingtongxia 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.
