摘要:
本文基于ABAQUS有限元软件建立了软土地区地表结构-土-隧道相互作用的非线性有限元模型，地表结构采用置于刚性筏板基础的单自由度体系模拟。考虑地表结构的有无，不同的土体模型及地震荷载，通过水平地震作用下的动力时程反应分析，研究了地表结构对盾构隧道周围土体以及衬砌地震响应的影响。研究表明，地表结构的存在会增大隧道周围土体地震响应，从而引起隧道结构变形以及动态内力的显著增加，同时发现采用弹塑性分析下的隧道地震响应大于采用黏弹性分析。因此，地表结构作用是影响盾构隧道响应的重要因素，综合分析地表结构-土-隧道作用下的结构动态响应有助于更合理的预测地震荷载下盾构隧道结构安全风险。
Abstract:
In this paper, a nonlinear numerical model accounts for the aboveground structure-soil-tunnel interaction in soft soil deposits was established based on finite element software ABAQUS, the aboveground structure was simulated using equivalent single degree of freedom oscillators, rested on rigid raft foundation. The influence of aboveground structure on the seismic response of lining and soil around the tunnel was studied through the dynamic time history analyses subjected to horizontal earthquake loading, accounting for the existence of aboveground structure, different soil models and earthquake inputs.The results reveal that the existence of aboveground structure can increase the seismic response of the soil around the tunnel, thus increasing the tunnel lining displacement and forces significantly.Moreover, the seismic response of elastoplastic analyses was generally higher than that of visco-elastic analyses. Therefore, aboveground structure effect is a critical factor for the seismic response of shield tunnel, it’s recommended to conduct comprehensive analyses for the aboveground structure-soil-tunnel system in order to better predict the risk for the shield tunnel structural safety.
