摘要
The seismic resilience measurements and performance recovery methods were investigated regarding the urban gas network. The skew of the recovery trajectory (SRT) and total recovery time (TRT) were introduced to quantitatively assess the efficiency and duration of the urban gas network system resilience in the technical dimension. Then the influence of different recovery methods were analyzed and discussed.Firstly, the resilience in technique dimension were defined in two ways according to whether the pipeline diameter is considered or not.To reflect the difference of recovery trajectory owing to the repair sequence uncertainty, the Monte Carlo method was applied to randomly simulate the network failure distribution location and repair sequence regarding a city gas network system in China.Furthermore, the influence of the different repair resources on resilience under different earthquake intensities conditions were analyzed by index SRT and TRT.Finally, three repair methods:point-by-point, whole-tube replacement, and hybrid repair (under optimal cost) method were compared for their influence on the resilience of the gas network. The results indicated that the increasing repair resources input could reduce TRT and SRT, and improve the recovery efficiency.With different damage degree, the influence of resources on the system resilience also varies.Under different earthquake intensity, the mixed recovery method has the lowest cost.When there are less ruptures on pipes conditioned on lower earthquake intensity, using the point-by-point recovery method costs less time and having the best recovery efficiency.On the other hand, the recovery time, efficiency, and the cost of the system are better than that of the point-by-point recovery method when whole-tube replacement or hybrid repair method is selected for high intensity condition. © 2021, The Editorial Board of Journal of Basic Science and Engineering.
