摘要
以横向有接头地下综合管廊非一致激励振动台试验为基础,基于有限元软件ABAQUS,建立了土-地下综合管廊结构数值模型,采用非线性弹簧单元模拟地下综合管廊的接头。分析了模型箱的边界效应、加速度响应、位移响应、以及管廊接头响应,有限元计算结果与试验实测结果进行对比分析,二者对比结果呈一致趋势,非线性弹簧单元可为生命线工程结构接头数值模拟提供了新思路。
Based on shaking table test of underground tions on the transverse direction, numerical modeling ABAQUS platform. The joints of the utility tunnel were lation. Then boundary effect of the laminar shear box, utility tunnel with joints under non-uniform seismic excita- of soil-underground utility tunnel was established on the modeled as nonlinear spring element in the numerical simu- acceleration response, displacement response and the joint effect of the UUT were analyzed. Finally, FE calculation results and the shaking table test records are compared in detail. The comparison results show that the simulation results are consistent with the test records. Therefore, non- linear spring element can be taken as a new method to the joint analysis.
