摘要为研究在一致、非一致激励振动台试验中不同箱体内土体、管道地震响应的异同，基于已经开发的悬挂式连续体模型箱开展了一系列多台阵振动台试验。对不同箱体中土体、管道的加速度以及管道应变等试验数据进行了分析，结果表明：(1) 在一致激励不同加载等级下，不同箱体中土体表面各监测点的位移时程曲线基本一致，而在非一致激励下，不同箱体中土体表面各监测点的位移时程曲线差异明显。各箱内土体间产生了明显的纵向相对位移，土体被拉裂，且在地震动作用后均产生了较大的残余位移；(2) 与一致激励下相比，非一致激励下各箱内管道及其周围土体之间均产生了明显的相对位移，造成了管道应变的增大，其峰值应变是一致激励下的2倍左右；(3) 在一致激励下，各箱体内土体、管道的地震响应基本相同，非一致激励下不同箱体内土体、管道的地震响应虽然存在差异，但各箱体内管–土地震响应规律基本相同。

Abstract：The seismic response of buried pipelines under longitudinal uniform and non-uniform excitations was investigated to explore the similarities and differences of soil and pipeline seismic responses in different boxes by employing the multi-point shaking table tests. The test data of soils and pipelines in different boxes were analyzed and studied in terms of acceleration and pipeline strain. The results show that：(1) The displacement time-history curves of the soil surfaces in different boxes are similar under uniform excitation with different loading levels. Under non-uniform excitation，however，the displacement time-history curves of the soil surfaces in different boxes are significantly different. Obvious longitudinal relative displacements occur between the soils in each box，the soils are torn apart，and large residual displacements are produced after ground motions. (2) Compared with the uniform excitation，there is obvious relative displacement between the pipelines and the surrounding soil under the non-uniform excitation，which results in the increase of the pipeline strain with a peak value about twice that under the uniform excitation. (3) Under uniform excitation，the seismic responses of the pipelines are similar to the response of the soil. Under the non-uniform excitation，the seismic responses of soil and pipeline in different boxes are different，but the seismic response laws of soil and pipeline in each box are basically the same.
