Research On Safety Assessment Model Of Hydroelectric Construction Site With DEMATEL And ANP

Along with the rapid development of our national economy, China's hydropower engineering construction industry is also in rapid development, from confusion to adaption, from spontaneous to productive, the performance is very considerable. But looking at the total conditions of our country's hydropower engineering construction industry, it is known that the proportion of various fatal and injury accidents caused by hydropower engineering construction is still high. Superficially, these casualty accidents are mostly caused by the people's illegal behavior, but investigating its deep reason, we will find that most of the accidents exist some of the defects and hidden dangers of accidents in safety management. Therefore, how to improve the water conservancy and hydropower engineering construction safety management level is the current hydropower engineering construction enterprise's primary and urgent task.The characteristics of the construction site in our hydropower engineering are studied in first in this dissertation. According to the water conservancy and hydropower engineering construction safety technology and related laws and regulations, standards, and other documents, and combined with expertise and practical conditions in the current hydropower engineering construction industry, the hydropower engineering construction site safety evaluation index system is established. And then the safety evaluation actualities are investigated in deep both at home and abroad, and the advantages and disadvantages and the discrepancies of the current safety evaluation methods are analyzed systematically, and a safety assessment method: DEMATEL-ANP method suitable for hydropower engineering construction site is put forward. Although DEMATEL method could calculate the degree of influences between the safety evaluation indexes, the weight of all the safety evaluation indexes are seen as the same during the process of computation. Therefore, combining DEMATEL method and ANP method, this paper confirms the degree of influences between the safety evaluation indexes by DEMATEL method and obtains the weight of the safety evaluation indexes by ANP method, and establishes the hydropower engineering construction site safety evaluation model with DEMATEL and ANP. And then the sorting of mixed weight is got, which provides analysis basis for the construction enterprise'safety management.
