既有给排水管线的震害及管道抗震能力关键问题综合分析

Comprehensive Analysis of Seismic Hazard to Existing Water and Wastewater Pipelines and Key Issues of Seismic Capacity of Pipelines

近年来我国和世界各地地震频发,地震活动进入多发期,对城镇生命线管道结构的安全造成很大威胁,管道结构的抗震能力亟待提高。针对上述情况,开展对城镇既有市政给排水管线震害的归纳总结,对相关问题进行深入的综合分析。在此基础上,分析阐述增强管道结构抗震能力和在抗震设计时应关注的要点问题。

In recent years,there are a high number of earthquakes in China and around the world,and theearthquake activity is in multiple phases,which will cause a great threat to the safety of the town lifeline – pipeline structure.It is urgently to improve the seismic capacity of pipeline structure.Aiming at the above situation,the article sums up and concludes the seismic hazards to the existing town municipal water and wastewater pipelines,and comprehensively analyzes the relative issues.On this basis,the article analyzes and sets forth the strengthening of the seismic capacity of pipeline structure and the key issues for attention in the seismic design.
