Comprehensive Evaluation Analysis And Countermeasures Study On Wharf Of Three Georges Reservoir

With the three gorges reservoir operation, the navigation condition has improved greatly, and with the rapid development of economy, water transport market very prosperity, ship large-scale development trends are also increasingly obvious. However, most of the existing wharf had run in decades, not only the three gorges reservoir brings change about natural condition and the safety operation of wharf will produce certain effect, but also the existing conditions of structural type, handling technology, personnel quality and so on had fallen behind relatively. In this case, potential safety hazard of ship large-scale is more and more serious. Therefore, it is imperative to establish a scientific evaluation system and methods to evaluate the dock safety and meet the requirements of the safe operation dock.Safety assessment is on the basis of risk identification,to take possibility of risk happening and its ponderance into account,and to provide risk control measures.The paper rests on the wharf of the three gorges reservoir area analysis and the future predict, adopting the model analysis and the computation unify to the wharf safety. Firstly, we analyze the related factors on the wharf security, namely natural condition factor, handling technology factor, anchorage capacity factor and the management level factors; second, by analyzing these factors, set up a set of three gorges reservoir dock safety for the comprehensive evaluation index system, used the Analytic Hierarchy Process and fuzzy comprehensive evaluation method for reservoir dock safety assessment; finally, through empirical analysis, inspect the suitability and effectiveness about the evaluation index system and evaluation method, and provide reference improvement measures and suggestions for the safety operation of wharf.
