The Study Of Real-time Monitoring And Early Warning System For Underwater Riprap Implantation Morphology

With the continuous development of the infrastructure construction of China slipping,waterway regulation project becomes increasingly important today.Jingjiang river is a significant section of the Yangtze River valley which is known as the golden waterway.Due to the severe evolution of riverbed,frequent change of bottomland,navigation channel is very unstable and the obstruction to navigation have occurred frequently.There is still a large gap between the existing conditions of the Jingjiang reach and the growing needs of the waterway transport economy along the Yangtze River.It needs to improve navigation conditions urgently.In order to alleviate the adverse situation of Jingjiang river channel,waterway department has begun to implement the waterway regulation project for some important shallow risk channel.A large number of "riprap ballast" measures were used to ensure the stability of river bank and river shoal in the regulation project.Due to the current construction ship positioning accuracy is not high,construction area of the great water depth,underwater definition is very poor,ripraps' diameter are not uniform,these cause the ripraps can't be distributed uniformly in the river bed,even produce missed throwing area,cannot achieve the desired regulationeffect.This has become a technical problem in the whole regulation project.To ensure the implantation site of riprap under the action of current,make real monitoring on riprap implantation morphology in construction and timely repair leakage parabolic area,need to research and develop a kind of underwater riprap implantation form real-time monitoring system software,make comparative analysis of before and after the riprap underwater terrain,timely feedback drain cast,less litter,exceeds the allowable range in riprap construction area and provide early warning.This project has been combined Jingjiang river channel regulation works,by studying general situation and the characteristics of the project in reach,researching on construction site,having conducted the research to the problems which need to be solved in this paper,the functional requirements of the system is clear.According to the system requirements,the overall design of the system software is determined,and the system software is formed and optimized from the aspects of the principle,structure,function and operation,the main program of software realization is given.Finally,the system is tested and run,and the test and operation results are analyzed in detail.These results demonstrate the correctness of the design of the system software,can achieve the desired goal,to meet the functional requirements.
