  • An explosion in the subway station will lead to huge losses of personnel and property. In order to study the response law of subway platform and surrounding rock of a subway station project in Shanghai under the action of solid explosive explosion, HJC model is embedded in the open source material point method program. The results show that the response pressure of platform roof and floor will decrease rapidly after reaching the peak in a short time under the influence of explosion wave, and the platform structure forms tension zone and compression zone during explosion. Due to the superposition of stress wave and reflected wave, overpressure sudden change zone will appear at the platform side wall. The whole platform structure sink under explosion. Moreover, the surrounding rock directly below the detonation point forms a collapse pit, and the surrounding rock directly above the detonation point and the station structure rises up. The damaged area is mainly concentrated in the bottom plate of the structure, and the damaged area is oval. The blast resistance of platform with column area is stronger than that without column area.
