- Abstract:
- A preliminary study on the function restoration of lifeline systems including electricity,communication,water and gas was made after earthquake in this paper.Considering the lack of investigation datum on the function recovery of the lifelines with the time in China,an exponential form of the post-earthquake function recovery function which combined with the characteristics of the lifelines system itself was established based on the survey datum on the function recovery of the four lifelines system(the power supply,communication,water supply and gas supply)in the Miyagi earthquake and the Great Hanshin earthquake occurred in Japan.A function recovery attenuation index that reflects the important degree of the lifeline system,the degree of difficulty in repairing and the effectiveness of the post-earthquake emergency decision repair measures was defined in the function.The value interval and selecting principle of the attenuation index of four systems were preliminarily limited on the basis of summarizing the earthquake damage characteristics of lifeline systems in China.In addition,the actual recovery time of power supply,communication,water supply after the Tangshan earthquake and gas supply in the Mianyang city after the Wenchuan earthquake was compared with calculation of the function recovery function.The two groups of data were in good agreement,indicating the lifeline recovery function that developed in this study is effective.
