摘　　要：在钢制波纹管廊在一般场地的振动台缩尺模型试验研究基础上,基于ABAQUS利用时程分析法分析预制装配式钢制波纹管廊的抗震性能,并与振动台模型试验结果进行对比。数值模拟和试验结果加速度时程吻合较好,加速度放大系数及其傅里叶幅值谱规律一致,验证了有限元模型的合理性。利用验证合理的数值模型,通过改变埋深、场地条件、地震方向等参数,对管廊和土之间相互作用的机理进行了参数分析;结合国内外规范抗震设计方法,利用振动台试验和数值模拟结果,提出了考虑土-钢相互作用的钢制波纹管廊抗震计算方法并给出了算例。In this paper,based on an experimental study of the corrugated steel utility tunnel on general ground,the time-history analysis method in ABAQUS is used to analyze the seismic behavior of prefabricated corrugated steel utility tunnels.The results are compared with shaking table test results.The results of numerical simulation and experiment agree well in the time-history of acceleration.The acceleration amplification coefficient and its Fourier amplitude spectrum are consistent,which verifies the rationality of the finite element model.The mechanism of interaction between the utility tunnel and soil is analyzed with consideration of burial depth,site condition and seismic direction by using a reasonable numerical model.Combining some Chinese and foreign codes,the results of shaking table test and numerical simulation,a calculation method is proposed for corrugated steel utility tunnels considering the soil-steel interaction.At last,an example is provided for verfication.
