- Abstract
Effectively evaluating the safety on the structure of large diameter PCCP pipeline broken wires and taking effective measures to repair are the ways to reduce the safety risk of broken wires during South to North Water Diversion Project large diameter PCCP pipeline operation. Based on the method of analytic hierarchy process, the hierarchy analysis mathematical evaluation model is established. The possible factors of the influences of various of South to North Water Diversion Project of underground large diameter PCCP pipe broken wires are scored by experts. At the same time, the PCCP pipeline safety failure judgment criterion and the judgment standard are established through the numerical simulation. The quantification of safety risk assessment of large diameter PCCP pipe is realized. A specific PCCP North South Pipeline engineering safety running and risk management software is developed. With real-time monitoring automation technology and the risk management system of Web-GIS, the software can perform real-time acquisition of the monitoring data, data file of electronic management and dynamic assessment and early warming of safety risk.
