摘要

为研究多点地震激励下埋地油气管道的地震响应，设计并制作缩尺埋地油气管道及周围土体模型，利用双台阵地震模拟振动台对其进行纵向一致及多点地震激励下的地震响应研究，分析纵向多点地震激励时不同地震动各加载工况下埋地油气管道土体加速度、位移及管道加速度、应变等地震响应的变化规律。结果表明：土箱内不同深度测点位移增量不同，致使土体间产生剪切效应，多点激励时土体变形及破坏程度相较于一致激励明显；土体加速度峰值随加载等级的提高呈增长状态，多点激励时箱内土体加速度峰值变化曲线一致性较差，土体加速度响应产生较大差异；随着加载等级的提高，管道与土体间加速度峰值差值逐渐增大，多点激励会造成管道加速度峰值产生滞后现象；管道顶部轴向应变随管轴表现为两侧小，中间大，多点激励时管道应变增长速率更快，产生的应变更大。

Abstract

Seismic analysis of long transport oil and gas pipelines is an important factor affecting the seismic design of the pipeline. The study of the seismic response of oil and gas pipelines under spatially correlated multi-point action will provide a theoretical basis for it. In this paper， a scaled-down model of a buried oil and gas pipeline is designed and fabricated. Shaking table tests were conducted to analyze the trends of seismic response of buried oil and gas pipelines and soil with increasing loading levels during longitudinal multi-point excitation. The final results show that： the displacement of each measurement point along the height in the soil box is different， and the shear effect between the soil bodies is especially obvious during multi-point excitation； The comparison of the peak accelerations of the soil and the pipe shows that the peak accelerations of both increases with the increase of the loading level， and the difference between the peak accelerations peaks increases continuously； Multi-point excitation will cause hysteresis for the peak acceleration of the pipe； The axial strain at the top of the pipe is smaller on both sides and larger in the middle along the pipe axis， and the strain of the pipe grows faster and generates a larger strain during multi-point excitation.
