| 中文摘要: |
| 本文结合近场波动数值模拟的解耦方法和随机有限元方法，提出了一种可考虑介质随机性的时域土-结构体系地震反应分析的解耦方法，此方法的给出为在场地及结构地震反应分析中考虑场地介质及结构参数的随机性的影响提供了较高精度且便于应用的理论方法。本文还以小湾拱坝为例分析了考虑介质随机性时结构的地震反应。 |
| 英文摘要: |
| Based on the uncoupled method for numerical simulation of near-field wave motion and stochastic finite element method, a new uncoupled method is proposed to analyze the seismic response of soil-structure system in time domain considering the stochastic characteristics of medium. By using this method, the radiation effect of wave energy to infinite field is simulated and the stochastic characteristics of complicated medium are being considered. This method is applied to analyze the earthquake response of the arch dam in Xiaowan Project. |
