Research on the explosion-proof design scheme of ancillary facilities for metro stations
The ancillary facilities of the metro station construction plan will be greatly affected when the located environment of the metro station area is relatively complicated,such as entrances and exits,ventilation pavilions,etc.;encounter buildings and structures such as factories,fueling stations,and pressure relief ports in underground spaces.This article primarily studies how to design ancillary facilities in complicated situations surrounding metro stations by analyzing explosion impacts.The impact range of an explosion from a fueling station is calculated and checked according to the G.M.Likhoff method,indicating that the requirements for the safe distance of the ancillary facilities of the metro station in the relevant specifications are reasonable.The setting and harmfulness of the pressure relief opening are discussed to provide a safety basis for ancillary facilities designs of metro stations.This paper also analyzes the general treatment method when the ancillary facilities of the metro station when encountering fueling stations in case studies.Among them,the danger of the pressure relief opening can be analogized to the fueling station,but its explosive shock wave does not directly face the ancillary facilities of the metro station,thus the degree of influence is relatively minimized,and the safety treatment measures can also be analogized to the fueling station.Unlike other civil buildings,the research shows that the metro station is more of a building or structure that undertakes a public transportation function,and its social impact needs to be considered.Therefore,it should be avoided as much as possible when encountering sources of public safety hazards.
