拉西瓦高拱坝水弹性模型基础确定

高拱坝水弹性模型可以很好的模拟“动荷载-结构-水-地基”四位一体的流固耦联系统，并能为高拱坝振动的研究提供可靠的实验数据，而水弹性模型对原型结构模拟的基础的范围直接影响实验结果的精度和准确度。以黄河拉西瓦拱坝水弹性模型为例，确定其模型模拟的基础的范围，并结合已有工程的水弹性模型基础的确定，进行比较和分析。

Research on the Hydro-Elastic Model Basis of Laxiwa High Arch Dam

Hydro-elastic model of high arch dam can effectively simulate the coupling system of fluid and structure of dynamic-load, structure, water and foundation, and can offer reliable experiment data for the research of vibration of the high arch dam. But the scope of the hydroelectric model basis of the simulated structure will directly influence the accuracy and precision of the experiment result. With the target of the hydro-elastic model of Yellow River Laxiwa Arch Dam, the scope of the model basis simulated is determined, and the results are analyzed and compared with those of stimulation by hydro-elastic model for the other projects constructed.
