Research Of Rivers Flood Prevention Engneering Influence Appraisal Factor Analysis

As the the main line of the Guidelines for the preparation, the article China's rivers for more and more construction projects, flood control on the river more and more serious impact on the trend, and river construction project management evaluation of the status of the relatively weak, should be made to establish an effective River flood control project construction impact assessment mechanism. And to the author for completion and participation in the evaluation of more than 10 items of flood prevention works practical experience as a guide, the evaluation of flood control on the content, methods and steps, section by section-by-point evaluation of key factors, the sensitivity analysis parameters discussed. And different types of flood control projects to analyze the focus of the evaluation, to the more important for flood control projects in addition to its recommendations should be carried out test model, the calculation should also evaluate the experience factor to the formula and numerical simulation of comparative analysis, to lease through science , Rational, standardized evaluation of the flood control work to strengthen the management of river construction projects.Reduce flooding hidden dangers.In theory analysis on the basis of Fugu bend to the Yellow River Bridge impact assessment of flood control projects as an example, its impact on a comprehensive evaluation of flood protection. Based on the focus of the project evaluation factors, the focus on the evolution of river silt, the choice of design flood, the water line project and other factors carried out a detailed analysis, that the proposed bridge near the river in a stable horizontal, vertical deposition in a state of the conclusions. Another Xian Te involved in the completion of the new hub of the Northern Link Road Project Saburo Weihe River Bridge in flood affected villages model tests carried out briefly, that the use of empirical formula calculated using the bridge backwater results and the river bed of the bridge backwater model test results Closer, and so conclude that numerical simulation, physical model test of impact assessment of river flood protection is necessary for flood control work in the future to provide guidance.
