| 中文摘要: |
| 提出了拱坝自由场地地震动的模拟方法，这种方法能反映地震动的空间相关性、随机性、传播性，同时能考虑地震动沿河谷高程的强度放大和水平方向的强度衰减，有望为拱坝动力分析提供较为合理的地震输入。 |
| 英文摘要: |
| In this paper, a simulation method of multi-point ground motion for free field of arch dam is proposed. The ground motion time history generated with this method accord reflects the spatial correlative, random and propagative characteristics and at the same time the magnification and attenuation of intensity along the depth of river valley and horizontal direction are to be considered. |
