本文提出了在研究重力坝抗震问题时以马尔柯夫谱作为地震动输入的随机模型。结合万家寨水利枢纽工程的重力坝,研究了重力坝的地震反应。研究结果表明,将马尔柯夫谱模型用于重力坝的抗震研究是可行的。
This paper presents a stochastic model based on Markov spectrum as a ground motion input when studying the gravity dam aseismic problem. Combined with the gravity dam of Wanjiazhai Water Control Project, the seismic response of gravity dam is studied. The results show that it is feasible to apply the Markov model to seismic study of gravity dam.
