摘要

    摘要
  • 摘要: 在中国城市轨道交通快速发展的推动下,隧道等地下结构近距离下穿地表建筑物的案例越来越多。对于相互穿越工程,较多的关注在于隧道等地下结构动态施工对地表建筑物安全的影响,而忽视了隧道建成后对被穿越的地表临近建筑物抗震性能的影响。拟结合某实际工程,建立盾构隧道-土体-地表邻近框架结构相互作用体系二维数值计算模型,对比分析隧道与邻近框架结构相互之间地震响应影响规律。计算分析表明：①隧道的存在使隧道两侧土体表面出现一个地震响应放大区；②下穿隧道对地表框架结构的地震响应有部分影响,但影响程度有限；③地表结构的存在对隧道结构地震响应的影响较小,可忽略不计。研究成果可为地下结构的规划以及地表结构与地下结构的抗震设计提供参考。
    Abstract: Promoted by the rapid development of urban rail traffic in China, more and more cases of underground structures, such as tunnels, have crossed the surface buildings with very close distance. As to the intersecting project, much attention has been paid to the influence of dynamic construction of underground structures on the safety of the adjacent surface buildings, but that on the seismic response of the adjacent surface buildings is usually neglected. Based on a practical project, a coupled interaction calculation model for tunnel-soil-adjacent frame structure is established, and the influence of the tunnel and frame structures on their seismic response is analyzed. The calculation and analysis show that: (1) a seismic response enlarged zone occurs on soil surface; (2) the underlying tunnel has influence on the seismic response of the frame structures, but the influence extent is small; (3) the influence of the frame structures on the underlying tunnel is very small, which can be neglected. The research results may provide references for the planning of underground structures and the seismic design of surface buildings and underground structures.
