本文介紹了在坝体結构动力分析中利用靜力模型試驗結果的三个具体实例。这三个实例是:大头坝橫向地震力的分配、大头坝坝垜横向自振周期的研究及拱坝自振周期的确定。在后二个实例中用本文所述方法求得的結果,与动力模型試驗及坝体原型实測的結果相当接近。我們认为,这种方法值得在解决一般坝体結构的动力分析的其他問題中得到更广泛的应用。
In this paper, we introduce three concrete examples of using static model test results in dam structure dynamic analysis. The three examples are: the distribution of the lateral seismic force of Dadouba Dam, the study of the lateral natural vibration period of Dadouba Dam and the determination of the natural vibration period of arch dam. In the last two examples, the results obtained by the method described in this article are quite close to those obtained from the dynamic model test and the dam prototype measurement. In our opinion, this method deserves wider application in solving other problems of dynamic analysis of the general dam structure.
