| 摘 要： | 本文采用“自由振动法”,设计了一个等效单自由度振动体系,对某核电站基岩的阻尼特性进行了实验研究。通过对实验结果的整理、分析,得到了基岩阻尼系数C不是常数,而是与频率有关的结论。从而揭示了阻尼系数C的非线性性质,这对进一步研究岩石动态本构方程具有意义。同时,文中给出的阻尼系数C的数据,对工程设计也具有参考价值。

| Abstract: | The damping characteristics of the bedrock in a nuclear power station are studied experimentally by free vibration system with one degree of freedom. On the basis of a numeridal analysis of the results, we come to the conclusion that the damping coefitciemt C of the bedrock is not constant, but a function of the frequence. This conclusion indicates that the subject we studied has non-linear behaviour. This point of view seems to be useful especially for the further study of dynamic constiutive equations of the rock mass.Also the damping coeficient C reported in this paper is of referential value to the engineering design. |
