Abstract

This invention discloses a method and system for analyzing the damage caused by flood erosion to pipeline protection projects. Applied to the field of pipeline protection analysis technology, the method includes: determining the watershed where the pipeline is located and the mountainous area within that watershed; analyzing and evaluating the unit hydrograph and instantaneous unit hydrograph of the flood based on various types of rainfall data within the mountainous area, converting flood flow data to obtain flood flow data, and predicting flood characteristics; acquiring the pipeline's engineering characteristic information, analyzing the degree of flood damage to the pipeline based on the acquired flood characteristics, and obtaining damage mode analysis results; conducting pipeline damage probability analysis based on the flood probability and damage mode analysis results, obtaining damage probability analysis results, and issuing early warnings based on the damage probability analysis results. This solves the technical problem in existing technologies where it is difficult to predict the probability of pipeline damage under flood erosion and cannot quantitatively assess the risk of pipeline flood disasters.
