| 摘 要： | 利用有限元－边界元－无限边界元耦合模型（ＦＥ－ＢＥ－ＩＢＥ），分析了在ＥｌＣｅｎｔｒｏ地震分别作为 Ｐ、 ＳＶ 波入射条件下，半椭圆形河谷上沉积层的地震响应。还研究了有限元和边界元网格尺寸对计算精度的影响。计算结果表明：在给定河谷形态、尺寸和材料性质条件下，沉积层表面各点的响应显著放大。

| Abstract: | Utilizing the coupling model of finite elements, boundary elements and infinite boundary elements(FE--BE--IBE), seismic response of alluvial soil deposit on a semi-elliptical canyon under the incidence of EI-Centro earthquake as P and SV wayes was analyzed. The effects of mesh size of finite elements and boundary elements on numerical accuracy were also studied. Results show that response at surface points of the alluvial soil deposit are amplified significantly for given conditions of shape, dimension and material properties of the soil and the canyon. |
