廊体系地震响应分析,研究了综合管廊结构及其内部管道的响应特征,并简要评价了其抗震性能。
结果表明,地震作用下,综合管廊变形基本与周围土层一致,侧壁与底板连接部位为损伤最大位置,
而综合管廊内管道,与传统直埋管道相比,其地震应力响应大为降低。因此在设计时,应重点考虑综
合管廊本身的抗震问题。

Abstract: In order to study the safety of utility tunnel system under earthquake excitations,a reasonable model of typical utility tunnel system was built through numerical simulation trial analysis. Seismic response analysis was conducted using 7 natural ground motions with different spectrum. The dynamic response characteristics of utility tunnel and internal pipelines were studied,which provides a brief evaluation of anti-seismic performance. The results show that the deformation of utility tunnel is basically consistent with the surrounding soil. The connecting of the side wall and the bottom plate is the maximum damage position. Compared with traditional pipeline,the seismic stress response of internal pipeline of utility tunnel is greatly reduced. Thus,the focus of the design should be the seismic problem of the utility tunnel itself. Key words: utility tunnel; pipeline; finite element method; seismic response analysis; lifeline engineering
