为了确定合理的抗震设计方法或抗震性的研究方法,对土坝在地震时种种的振动现象能给出适当的预测,在进行解析方法的开发研究的同时。用实际坝的地震观测结果和土坝模型的振动实验结果进行验证。是必不可少的。模型实验方法,是取几个物理量相似的缩小模型 In order to determine a reasonable seismic design method or research method of earthquake resistance, we can make appropriate prediction on various kinds of vibration phenomena of earth dam during earthquakes, and at the same time, carry out the research and development of analytical methods. The actual dam earthquake observation results and the earth dam model vibration test results were verified. Is essential. Model experiment method is to take a few similar reduction of the physical model
