Research On Security Risk Assessment And Security Measures Of The South-to-North Water Transfer Project

The South-to-North Water Diversion Project is a major strategic infrastructure which can ease the water shortages in northern China,optimize the water resources allocation,improve the ecological environment and it is an oversize water transfer project which across the rivers,provinces,industries.It has long line and many subprojects.Now,the eastern route project of the South-to-North Water Diversion Project has run nearly 2 years,the middle route has formally run at the end of 2014.In the process of the South-to-North Water Diversion Project running,the security issues which the South-to-North Water Diversion Project facing is no longer construction safety but to ensure the safety of project running.One of the significant issues is the public security risk.It can influence the engineering safety,water quality safety and security of personnel.In China,the research and application of risk evaluation is still in its infancy,the study on security risk evaluation is very few.Therefore,based on this study of public security risk evaluation of the South-to-North Water Diversion Project,this article will give some security measures and recommendations,then apply them to the project to solve the problems and to ensure the project run safely,effectively and persistently.At first,from the perspective of failure probability and failure consequence,this article established the public security risk evaluation index system for Various Projects in South-to-North Water Transfer Project by means of field research,collecting data,interviewing the experts,starting brainstorming and giving full play to expert intellectual resources,combined with the South-North Water Transfer Project feedback of management unit to selection and refinement of evaluation indicators;Then,this article analyzed the South-to-North Water Diversion Project by using layer analysis--synthesis unclear judging method.This article got the index system of the comprehensive weight by layer analysis and analyzed the risk levels of different parts by synthesis unclear judging method,and divided the South-to-North Water Diversion Project risk level.Finally,based on different risk levels and the national conditions,this article came up with some security measures and recommendations from the point of civil defense,material defense and technical defense.This research not only has a positive effect on public security prevention of the South-to-North Water Diversion Project but also can give references to the public security prevention of other water conservancy projects.
