摘要
提出一种在Love波和Rayleigh波作用下分析频域内横跨沟槽管线的横向与纵向反应方法,分析管线刚度与场地阻尼对其反应的影响。还提出一种计算沟槽附近场地动力格林函数的近似方法,并就其对精度的影响进行研究。分析结果说明,横跨沟槽的管线在地震时的响应可能比无沟槽时大得多,应引起注意
An approximate method has been used to calculate the Green function of the layered site with canyon, and further to analyze the lateral and transverse response of pipeline laid over the canyon induced by Love and Rayleigh waves. The adaptation of the method has also been discussed. From the results obtained we can see that seismic response of the pipeline laid over the canyon can be much larger than that without canyon.
