Abstract
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.
