To study the seismic response of buried pipelines with the high drop, a small-size test based on shaking table was conducted to analyze the effects of pipeline wall thickness, pipeline diameter and inclination angle on the seismic response of buried pipelines with high drop. Meanwhile, a finite element model was proposed for numerical simulation. The research results show that the peak axial strain of the pipeline increases with the decrease of the thickness and the diameter of the pipeline in the action of seismic waves and the increase of the inclination of the pipeline. Based on the results of experiments and finite element simulations, a regression equation of the peak axial strain of buried pipelines with the high drop was developed with the consideration of the effects of the ratio of wall diameter to wall thickness and height. Meanwhile, some valuable conclusions were obtained for the instruction of the seismic design of pipelines in engineering.

为了研究高滴地埋管道的地震响应，进行了基于振动台的小型试验，以分析管道壁厚，管道直径和倾角对高滴地埋管道的地震响应的影响。同时，提出了有限元模型进行数值模拟。研究结果表明，在地震波的作用下，随着管道厚度和直径的减小，管道倾角的增加，管道的轴向峰值应变也随之增加。根据实验结果和有限元模拟结果，考虑壁径与壁厚和壁厚之比的影响，建立了高滴埋管道峰值轴向应变的回归方程。同时，
