The method and the device have the advantage that the method and the device for identifying the coupling hidden danger of the gas pipeline and the bridge and evaluating the corresponding risk are provided.

Description

technical field [0001] The invention relates to the technical field of gas safety supervision, and more specifically relates to a method and device for identifying and evaluating hidden dangers of gas pipeline-bridge coupling. Background technique [0002] As the urbanization process continues to intensify, cities are facing more and more public security risks, which pose a huge threat to the normal development of urban society and economy. Because of the interdependence and mutual restriction within and between social systems, chain effects often occur, which shows that the occurrence of disasters together will trigger a series of secondary disasters. When the two risks converge, their uncertainty is magnified. Its influence will also spread from one geographical space to another wider geographical space. [0003] The construction of municipal engineering in recent years has made the lifeline project and the construction of urban roads and bridges more closely linked and ...
