| 中文摘要: |
| 基于典型的南京软土场地条件,建立地铁地下车站—土体—高层建筑系统二维非线性有限元分析模型,研究了两层三跨岛式地铁地下车站结构对邻近高层建筑地震加速度反应的影响规律.结果表明:地铁地下车站使高层建筑与地表接触位置的地表加速度反应动力系数谱谱值在周期0.5~3 s范围有所增大,建筑各层的峰值加速度反应基本上均有所增大,局部楼层的峰值加速度反应增大达43.7%.随高层建筑与地铁车站间距的增大,该影响逐渐减小.若高层建筑分别采用桩基础/筏板基础,间距与地铁地下车站宽度之比D/B≥1,而D/B≥0.75时该影响可以忽略. |

| The two-dimensional finite element analysis models based on the Nanjing soft soil site of subway station,soil and high rise building are created to research the seismic acceleration response influence of high rise building nearby two-layer three-stride island-type subway station.The results show that the ground acceleration response dynamic coefficient β spectrum value in the cycle of 0.5~3 s range on the contact point of ground and building are increased.The peak acceleration response of the vast majority of the floors is increased,and the partial floor is increased by 43.7%.The influence decreases when the space between high-rise building and subway station increases,and if the high-rise building is with pile foundation/raft foundation,the influence can be ignored when the ratio of the space to width of underground subway station is 1/0.75. |
