| 摘 要： | 研究了局部场地条件对地震波的散射效应，对拱坝－地基体系在不均匀散射场和均匀输入场地震作用下的动力时程响应进行了对比分析。对小湾拱坝的实际分析表明，局部场地条件对地震波的散射效应对于拱坝的应力分布的峰值大小的影响是不容忽视的，甚至是至关重要的。

| Abstract: | The scattering of the seismic waves by the local field is investigated, and its effects on the analysis of the dam foundation dynamic interaction in the time domain are studied while compared with the corresponding analysis neglecting the scattering. The comparison shows that the scattering field of the seismic waves have great effects on the stresses distribution and the amplitude of the arch dam. |
