Safety Management Of Project Construction Phase Duirng The Flood Of Temporary Navigation

Since China was founded, a batch of hydraulic project and other waterinfrastructure had been built. These project made great contribution for theconstruction of flood control, power generation for our country, irrigation, tourism,shipping and water supply. Inland water transportation industry achieve rapiddevelopment, promote the construction of hydraulic project and bring considerableeconomic value, etc. But in a navigation requirements of the hydaulic projectconstruction process, would cause the changes of the navigation environment, inaddition, in the hydraulic project construction, the waterway vessel traffic flow pastincrease, navigation environment become complicated, easy to cause the safe hiddentrouble of the water traffic accident. For example in the hydraulic project construction,temporary navigation safety management issues. Therefore, it must be consideredabout these problems to the project construction influence.This paper selects the management of xiangjiang,changsha multi-purpose projecttemporary navigation safety as the research object, use safety engineering and earlywarning management theory, analysis the features of the project, through theinvestigation and analysis of the calculation about the construction process of theflow field, discusses the temporary navigation safety management system and putsforward the specific measure.Analyzing the navigation safety system structure of the building on shippingsystem to person -the ship-environment constitute a organic whole, combined with themeans of safety management. And, on the basis, uses the preliminary harmfulnessmethod (PHA method) and causal analysis method of technical means, find temporarynavigation safety of facing danger factors and analysis the important degree.Through the safety of navigation on temporary factors analysis during the floodperiod and establish a safety warning to ensure the safety of engineering and the pastship or accident loss is reduced to a minimum. Based on the comprehensive hub of thechangsha construction，calculated the temporary shipping within the scope of the flowfield to get the Q-Z-Vprofile, according to the temporary channel flow velocity of the corresponding surface to publish early warning level, provided the basis as temporarynavigation warning.
