| 摘 要： | 在进行长输埋地管道振动台试验的过程中,针对数据信息的采集量测以及传感器的布置位置进行了研究。采用三维数值模拟的方法对管-土相互作用体系进行了地震反应分析,内容包括埋地管道结构纵、横向在非一致地震动作用下的地震响应及受力变形特征。根据计算结果确定了主观测断面及辅助观测断面的位置及观测断面上传感器布置的位置,在满足基本信息采集要求的前提下,对可供采用的信息采集通道进行了优化分配,由此确定本次试验的观测断面以及传感器的具体测量部位与数目。成果对试验获得成功起到了保障作用,可为同类试验提供参考。

| Abstract: | The location scheme of the sensors in a shaking table test for a long distance buried pipeline was studied in this paper. The seismic response analyses of pipe-soil interaction were performed in this study by using a 3-D finite element model of the buried pipeline. The seismic response and dynamic characteristics of the buried pipeline under longitudinal and lateral ground motions were carefully investigated and subsequently used to determine the locations of the critical sections and auxiliary sections for deploying sensors. The location schemes of the sensors on those sections were selected according to the numerical results. The data acquisition channels were also optimized in order to effectively record necessary data during the tests. The monitoring sections as well as the number and location of the sensor were finally determined. The scheme of sensor locations played an important role in guaranteeing the success of the experiment, and also has some reference values for similar experiments in the future. |
