摘要
采用时程分析法对地震作用下长输管线的动力响应进行分析,并探讨了管线悬跨段长度、地震强度、几何非线性等因素对其地震响应的影响.结果表明,地震作用下,管线的位移和应力响应曲线随时间的变化趋势基本一致;较长管线的振动周期较长;当地震强度较大、管线较长时,管线考虑大变形和不考虑大变形的地震响应存在较大差异.
Time history method was used to study the dynamic response of long-distance pipeline under the action of earthquake.The factors of earthquake response of pipeline was discussed,including the length of pipeline,intensity of earthquake,geometrical nonlinear,etc.The results show that the variation trend of displacement response curves of pipeline consistent with the stress response curves.The vibration period of the longer pipeline is longer.These is great difference among the earthquake responses of long-distance pipeline consider or does not consider the large deformation effect,if the earthquake intensity is great.
