摘要
由于施工质量、裂缝等因素以及坝龄的增长,碗窑水库碾压混凝土大坝的物理力学参数也发生一定的改变。为了获取能够反映大坝当前实际情况的物理力学参数,采用混合模型反演方法对其进行反演分析,进而为大坝结构安全性态的分析评价提供依据。结果表明,所建混合模型精度高,反演的大坝整体综合弹性模合理、可信。
The material parameters of Wanyao RCC Dam is constantly changing because of construction quality and cracks and the in- crease in the dam＇s age. For the parameters that can reflect the reality , an inverse analysis is made by using the foundation of mixed models and it can provide evidence for an analysis and evaluation of dam structure safety behaviors. It shows that the fix precision of mixed model is good and the result is reasonable and believable.
