摘要针对立体交叉隧道结构地震动力响应特性及相互影响规律等问题，在三向El地震波作用下完成了3种地震烈度、6个工况的交叉隧道振动台试验，试验结果表明：地震烈度越高，隧道各特征点的地震加速度、环向应变越大，在Ⅸ度三向El波作用下，沿上跨隧道墙脚轴线方向，交叉中心断面处最大地震加速度比普通断面(受相邻隧道影响小)小，而环向应变比普通断面大，沿下穿隧道拱腰轴线方向，交叉中心断面处最大加速度比普通断面大，而最大应变比普通断面小。通过建立三维数值模型与试验结果进行了相互验证，数值计算表明：在Ⅸ度三向El波作用下，沿上跨隧道轴向，交叉中心断面处各特征点σ1、σ3及主震方向位移最大值均比普通断面大，沿下穿隧道轴向，交叉中心断面处各特征点σ1、σ3及主震方向位移最大值均比普通断面小。

Abstract：Aiming at problems of seismic response features and their mutual influence laws of a 3-D cross tunnel structure, shaking table tests were conducted for its model under El seismic waves in 3 directions and 6 working conditions with 3 seismic intensities.The test results showed that the higher the seismic intensity, the larger the seismic acceleration and axial strain at the tunnel’s feature points;under El waves in 3 directions and the seismic intensity 9, along the axis of upper tunnel side wall bottom, the maximum seismic acceleration of the cross center section is less than that of a common section, while the maximum hoop strain of the cross center section is larger than that of a common section;along the direction of arch haunch axis of the underpass tunnel, the maximum acceleration of the cross center section is larger than that of a common section, while the maximum axial strain is less than that of a common section. Then a 3-D numerical model was built and used to do numerical simulation.The simulation results were compared with testones to verify each other.The numerical results showed that under El waves in 3 directions and the seismic intensity 9, along the axial direction of upper tunnel, the maximum values of σ1, σ3 and displacement in the main seismic direction at various feature points of cross center section are larger than those of a common section; along the axial direction of the underpass tunnel, the maximum values of σ1, σ3 and displacement in the main seismic direction at various feature points of cross center section are smaller than those of acommon section.
