Construction of risk diagnosis mode database for South to North Water Transfer Project

There are complex and diverse engineering structures in the Middle Route Project of South to North Water Transfer. In order to ensure the normal operation of the project during the operation period. By analysing and summarizing the possible dangerous situations, it can effectively improve the emergency response ability of relevant management departments. In this paper, typical structures and risk databases are built based on the method of entity relationship graph. Using the related factors in the history risk databases, the engineering factors, environmental factors and human factors are sorted out to subdivide the entities. The relationship between risk factors and typical structures is carried out by risk codes, so as to build a complete engineering risk database.
