Buried pipeline risk assessment method and device based on fluid-structure interaction

The invention provides a buried pipeline risk assessment method and device based on fluid-structure interaction. The method comprises the following steps: determining a dangerous point in a buried pipeline to be evaluated, and screening out a target buried pipeline according to the dangerous point; determining fluid data corresponding to a target fluid domain and solid data corresponding to a target solid domain in the target buried pipeline; performing fluid-solid coupling processing on the fluid data and the solid data at the dangerous point to obtain internal and external damage data of the buried pipeline at the dangerous point; and performing risk assessment on the buried pipeline to be assessed according to the internal and external loss data of the buried pipeline at the dangerous point. Based on the method, buried pipeline risk assessment can be accurately and efficiently carried out. 本说明书提供了一种基于流固耦合的埋地管线风险评估方法和装置。该方法包括：确定待评估埋地管线中的危险点，并根据所述危险点筛选出目标埋地管线；确定所述目标埋地管线中目标流体域对应的流体数据和目标固体域对应的固体数据；将所述流体数据和所述固体
