摘要
文章依托广州地铁花都广场站—马鞍山公园站区间隧道工程,建立地铁隧道地震动力响应三维数值分析有限元模型,计算分析水平向地震荷载作用下的地表位移、隧道结构动力响应,并计算分析了不同阻尼、边界条件等计算参数对隧道结构动力响应的影响。
Based on the metro tunnel works of section between Huadu Square station - Ma＇anshan Park station of Guangzhou metro, the paper establishes a finite element model of 3D numerical analysis on seismic response, and it calculates and makes analysis of the surface displacement and tunnel structure dynamic response under lateral seismic loads, and analyzes the influence of different damping, boundary conditions and calculation parameters on the dynamic response of tunnel structures.
