Research on Safety Evaluation Model of the Main Underground Pipelines in Shanghai, China

With the rapid development of the economy in Shanghai—the metropolis in China, the density of the underground pipelines and the load of the pipeline network are increasing at a high rate. To guarantee the operation of the city properly, safety of Underground Pipeline. Network (UPN) must be one of the foremost considerations. In this paper, the authors present a method to assess the UPN safety in Shanghai by applying a newly designed Safety Grade Evaluation Model (SGEM). Furthermore, this paper provides a safety management system, which will optimize management of UPN, by applying a Rehabilitation Cost Model (RCM). At last, the authors design a roadmap for SGEM for future applications. The above models enhance efficient management of pipeline network in Shanghai which will be helpful to rapid development of the city.
