Research on the Rapid Risk Assessment System of Chemical Industrial Park Pipeline under Flood Water

Abstract

The rapid risk assessment for chemical industrial park is crucial to take timely and reasonable measures, eliminate potential safety hazard and avoid the domino accident when facing flood water disaster. This paper aims at the failure problem of the pipeline as the research key point, drawing on the mechanism of flood water’s impact force and wave force, the pipeline shows different failure behavior on condition of different the velocity and density of flood water, and the failure model of the impact force and wave force are established based on the vulnerability of the pipeline, and then the probability model is also built by defining the uncertainty parameters of the pipeline. At the same time, the large numbers of Monte Carlo operating is pre-processed, and the calculating result is saved into database by mean of matrix. Finally, an example is introduced to prove that the rapid risk assessment can be made based on input data of the real-time velocity and density of flood water.
