简要介绍了云南香格里拉、德钦—四川得荣交界5.9级地震,重点介绍了其烈度分布情况、房屋震害特征和生命线系统各工程结构的震害特征,讨论了此次地震生命线系统抽样调查点数量远小于房屋抽样点的合理性,最后得出了应根据不同地震的不同震害特征表现,确定各系统工程结构抽样调查点数量的结论。
This paper briefly introduces the 5.9 magnitude earthquake at Shangri-La, Deqin-Derong, Sichuan Province. The seismic intensity distribution, the damage characteristics of buildings and the seismic damage characteristics of the lifeline systems are introduced. The sampling points of the earthquake lifeline system The number is far less than the sampling point of the house, and finally concludes that the number of sampling points of each system engineering structure should be determined according to the characteristics of different earthquake damage characteristics.
