| With China’s sustained and stable economic growth, water conservancy and hydropower engineering industry is developing rapidly in the next a considerable period of time will be at the height of the construction, but accompanied by the rapid development of water conservancy and hydropower engineering industry from the water conservancy and hydropower project construction frequent accidents, causing huge casualties and property losses, significant impact on society. On the surface, causing the accidents are mostly due to improper operation or machinery damage caused by such acts, but their root cause of most accidents occur are due to an accident on the safety management risks. So how to improve the safety management level of water conservancy and hydropower project construction, improve construction safety management information level is the current water conservancy and hydropower construction enterprises urgent task.This paper studies China’s water conservancy and hydropower project construction site characteristics, in accordance with the relevant policies and regulations, water conservancy and hydropower construction safety management, combined with many expert opinions, detailed analysis of the construction of many of the advantages and disadvantages of the current safety assessment methods abroad and apply water conservancy and hydropower project range safety evaluation model eventually selected network analysis, using Super Decisions software to calculate the index weight. Water Resources and Hydropower Engineering Construction Safety Assessment and early warning information management and ensure construction safety conservancy and hydropower project preconditions and important measures. We consider the linear water project construction site has multiple, widely distributed, long front, safety data management difficulties in a comprehensive study, etc., with computer cloud technology, the establishment of a safety assessment for the core, including government departments, industry departments, construction units(including supervision), construction companies and security experts one of five water conservancy and hydropower construction safety management systems. Systems melting construction site security information management, safety assessment and early warning, plan management, teaching in one case, the use of computers to manage various construction safety message text, graphics, photographs, video, and security-related laws, regulations, policies, standards, emergency plans, typical cases, through information sharing, the government and the competent departments at any time inspection and supervision, and safety supervision can stand next to and reflect the overall security situation under regular supervision of construction, experts on information security management senior judge, evaluate and identify potential risks Construction companies can receive timely feedback and guidance, worker safety guidelines can also receive timely information, learning about the safe construction of knowledge, and the combination of site safety supervision, and ultimately comprehensive water conservancy and hydropower project, the whole process, the whole period of construction security management. |
