| 摘 要： | 考虑地震动的随机性,根据随机过程理论,提出一种简单的模拟平稳随机过程的地震动模型,并给出了确定模型参数的原则和方法。继而,将其应用于一均质土坝,并与K ana i谱和M arkov谱进行了比较,验证了该模型的合理性。同时,探讨了该土石坝在随机地震动激励下的地震反应。 |
| 关 键 词： | 随机地震动模型 平稳随机过程 功率谱 土石坝 |

| Abstract: | A stochastic seismic motion model is presented accounting for uncertain real seismic excitations in this paper. The principle and method of determining model parameters are given. Then, this model is used to analyze seismic response of a homogeneous earth-rock dam. The calculated results are compared with that obtained from Markov spectrum and Kanai spectrum. The rationality of presented stochastic seismic motion model is examined and certified. At the meantime, Seismic performances of the earth-rock dam excited by stochastic seismic load are analyzed. |
| Keywords: | stochastic seismic motion model stationary stochastic process power spectrum earth-rock dam |
