本文以青铜峡大坝电站坝段向上游变形这一“疑点”为例,采用结构计算及多种模型评估了其主要影响因素,并重点对渐变温度、泥沙以及扬压力所产生的时效对坝变形的影响作了深入的分析研究,由此基本弄清了上述“疑点”的物理成因.
Taking “Doubt” of upstream deformation of the dam section of Qingtongxia Dam as an example, the main influencing factors are evaluated by structural calculation and various models, with emphasis on the effects of gradual temperature, sediment, Dam deformation has made in-depth analysis of the study, which basically clarify the “doubt point” of the physical causes.
