摘要
以厦门市疏港路立交式双仓框架地道桥实际工程为背景,建立地道桥和基础之间的接触采用弹簧单元,赋予弹簧单元不同的刚度值及将地道桥底面各节点全约束的ANSYS有限元模型,采用大比例模型的静载试验和模态试验,从自振频率、挠度、应力3个方面的ANSYS有限元值与模型试验实测值之间进行对比分析,对有限元模型的建模方法进行正确性佐证,研究双仓框架地道桥结构理论分析时运用ANSYS有限元分析软件的合理性.
In this paper, taking double chamber tunnel bridge at Shugang Ave. in Xiamen City as background, contact spring element between the tunnel bridge and the foundation, and ANSYS-based finite element model that gives the spring element stiffness values are all established. The large scale models of static load test and modal test is used to verify feasibility of the finite element model from viewpoints of self vibration frequency, deflection.
