| description | The invention relates to the technical field of gas pipe network risk management, and provides a gas pipe network adjacent underground space risk assessment method and device. The method comprises the following steps: acquiring fuel gas leakage influence information of an evaluation unit in a fuel gas pipe network, fuel gas diffusion and aggregation information of an adjacent underground space of the evaluation unit, explosion influence information after fuel gas leakage and ignition information; based on the leakage influence information, the fuel gas diffusion and aggregation information, the explosion influence information and the ignition information, explosion risk index parameters after fuel gas leakage are determined; and determining a target risk level of each adjacent underground space based on the explosion risk index parameters. According to the method, the explosion risk of each adjacent underground space is quantitatively analyzed from the aspects of gas leakage, gas diffusion, gas gathering, the |
