摘要
采用有限单元法和多种数学模型对青铜峡大坝电站坝段的变形性态进行了系统分析 ,对影响坝段变形的主要因素进行了评估 ,对坝体自重、渐变温度、坝基扬压力以及长期荷载的时效对坝体变形的影响作了综合分析 .
Deformation behavior analysis for the power plant dam section of Qingtongxia Dam by using various models and evaluation of the primary influence factors of the structural calculation method are carried out. At last, the influence of time-effect components of the gradual temperature variation, sediment, and uplift pressure and etc ., is deeply analyzed.
