摘要
输电塔-线体系作为保障国民生产生活的基础设施,确保其安全可靠地运行具有重要的现实意义。多次地震灾害数据统计表明,地震作用下输电塔-线体系的易损性较高。主要从输电塔-线体系地震响应的动力分析模型、数值模拟及振动台模型试验3个方面,对现有的研究成果进行了系统阐述,并分析了输电塔-线体系动力分析模型及其研究方法的特点及存在的不足之处,对输电塔-线体系地震响应分析方法亟需解决的关键问题及未来研究的发展趋势进行了展望,为以后相关人员从事研究提供参考。
In order to provide for the national production and consumption,it is of practical significance to ensure the safe and reliable operation of the transmission tower-line system,as part of the infrastructure.The statistics of multiple earthquake disasters show that the system is highly vulnerable during seismic motions.We summarized research progress of the transmission tower-line system from aspects of dynamic analysis models of seismic response,numerical simulation and shaking table model test,and analyzed the characteristics and the existing deficiencies of dynamic analysis models and the research methods.And then the key issues needing immediate attention and the research prospect of seismic response analysis methods of transmission tower-line system were addressed,which laid the foundation for further study.
