摘要
通过数值模拟的方法,以天津地铁七号线外院附中站—榆关道站区间工程为研究对象,建立了地层及隧道结构相互作用三维空间模型,利用安评报告提供的时程曲线数据,通过三维时程分析的方法研究了邻近高铁盾构隧道在多遇地震E2和罕遇地震E3作用下高铁桥桩沉降、变形情况和隧道结构受力的状况,成功解决了临近高铁的盾构隧道在地震作用下高铁桥桩和隧道结构地震响应问题。
In this paper,by means of numerical simulation,taking the tunnel between Affiliated middle school of foreign language college Station and Yuguan Station of Tianjin metro line 7 for example,the 3D spatial model of the interaction of ground-tunnel structure is established. Based on time travel curve data of safety evaluation report and 3D time-course analysis method,under the action of frequently occurred earthquake( E2) and rarely occurred earthquake( E3),the settlement and deformation of the high speed railway bridge pile and the stress of the tunnel structure has been studied. It also successfully solved the problem of the response of earthquake between the shield tunnel structure and the pile of high speed railway.
