摘要

地震作用下地铁隧道与临近建筑物的动力相互作用问题已受到不少学者的关注和重视，但是针对软土场地方面的动力相互作用认识还不充分。本文以天津软土场地为例，采用Abaqus有限元软件围绕隧道与地上框架结构间距、隧道埋深、隧道上行线与下行线间距、框架结构自振频率等参数，对隧道-软土地基-地上框架结构体系地震响应问题进行了参数化分析。研究发现：地铁隧道会对其下穿的地上框架地震响应产生一定程度的扰动，以框架结构层间位移角计量这种扰动，影响程度在10%左右；地上框架结构可能会放大临近地铁隧道的动应力响应（特别是下穿型地铁隧道），也可能会削弱其动应力响应，就本文模型而言，地上结构对衬砌动应力峰值的放大倍数最高可达80.7%。建议软土场地工程设计中考虑地上建筑对下穿型地铁隧道抗震性能的不利影响。

Abstract

The problem of dynamic interaction between subway tunnels and adjacent buildings under earthquake has attracted much attention and concentration, however, the understanding of the dynamic interaction in soft sites is still insufficient.Taking Tianjin soft sites as an example, the Abaqus finite element software was used to analyze the seismic response of the tunnels-soft soil-above ground frame structure system, and a parametric analysis was conducted from aspects of the distance between tunnel and above ground frame structure, buried depth of tunnel, distance between paralleled tunnels, and natural frequency of the frame structure.The results show that subway tunnels will cause a certain degree of disturbance, about 10% by using the story drift ratio as a measure, to the seismic response of the ground structurel which they pass beneath.The above ground frame structure may amplify the dynamic stress response of adjacent subway tunnels (especially the underpass subway tunnel), but sometimes may also weaken the dynamic stress response.For the adopted model in this paper, the maximum amplification factor of the peak dynamic stress of the lining is up to 80.7%.It is suggested that the adverse effects of ground buildings on the seismic performance of underground tunnels should be taken into account in the engineering design in case of soft sites.
