| Abstract: | This paper first collects and sorts out the distribution areas of major gas supply facilities of Jingwei Gas Co., Ltd. and Shanxi Minsheng Natural Gas Co., Ltd in Yuncheng central city. According to the structure of the gas supply station and the pipeline structure, the damage of the portal station and pipeline under different seismic intensity is calculated, and the functional failure result is given eventually. The results of this study indicate that we must pay attention to the maintenance and construction of gas supply facilities to ensure that gas supply facilities basically maintain functions in the event of major disasters and prevent secondary disasters. |
