Abstract:
In order to evaluate the operational safety risk of municipal pipeline networks rapidly and scientifically, the operational safety accidents of pipeline networks were collected and analyzed by means of online survey and field investigations. Then, the accident influence mechanisms of key risk elements were studied, including third-party damage, corrosion, aging and temperature change. Based on this, the risk evaluation index system for operational safety of municipal pipeline networks was established. In the system, the index scores are determined by semi-quantitative method and the index weights are computed by analytic hierarchy process. Finally, test was conducted on a certain industrial park and the risk of gas pipeline network was assessed. It is shown that the scoring criteria of each index can be determined easily and operated conveniently, and its evaluation results are in accordance with the survey results, so this risk evaluation index system is applicable to the fast risk evaluation of municipal pipe networks.
