本文提出了二元并联体系结构的自振特性与地震荷载的分析方法,并用试验结果进行了论证分析,说明这种方法是可行的。同时对两个分体系的各主尺度不同时,对其自振特性、地震加速度分布指数的影响程度进行了研究。最后找到了大中型扬水站地震加速度分布指数的一般分布规律,从而提出了一种简单易行的扬水站地震荷载的计算方法。
In this paper, the self-vibration characteristics and seismic load analysis methods of the binary parallel architecture are proposed, and the results are demonstrated by the test results, which shows that this method is feasible. At the same time, the influence degree of the self-vibration characteristic and the seismic acceleration distribution index were studied when the main scales of the two sub-systems were not the same. Finally, the general distribution law of seismic acceleration distribution index for large and medium-sized lift stations was found, and a simple and easy calculation method for seismic load of lift stations was proposed.
