The Study Of Highway Bridge Overloaded Management

In recent years,China's highway infrastructure has achieved remarkable achievements,but with the economic interests of people driven in recent years,and the legal system is not perfect,the national road traffic illegal overloading,road traffic facilities in the past decade Has been quite amazing.Highway flooding overload will not only threaten people's travel safety,but also seriously damaged the transport facilities,improve road maintenance costs.It is of great economic and social significance to study the super highway measures and to explore the management methods of overloaded vehicles.In this paper,the research status quo of highway bridge super-management at home and abroad is investigated,and the effects of weighting,administrative enforcement and joint control are discussed.The inspection of inspection station and the control of loading link are discussed.Taking the beam bridge overloaded management work in Beijing as an example,this paper discusses the working methods of vehicle overloading,and discusses the government 's grasping,joint enforcement,comprehensive management and integration mechanism and points out the deficiency and related management suggestions.This paper discusses the specific method of the bridge management.The bridge safety assessment and early-warning model are established through the real-time monitoring data,and the decision-making basis is provided for the management department to make the corresponding treatment through the safety early warning system.Real-time monitoring of the structure dynamic response records the bridge and environment,The wind speed,the humidity,the traffic volume,the structural stress(strain),the structure deformation and so on the influence;May carry on the traffic management reasonably,the effective measure inspects the bridge structure movement status,safeguards the bridge security.Discusses the super-management method of arch bridge.The safety evaluation of the bridge is made by combining the trend forecasting and the analytic hierarchy process.The safety and reliability of the combined method is objective and reliable,and the degradation degree and rate of the safety performance of the structure can be predicted effectively during the whole health monitoring.Data acquisition system is responsible for real-time monitoring of the bridge data acquisition on-site acquisition;data transmission system is responsible for the acquisition system to collect data transmitted to the central server database;data analysis system is responsible for the collection of various types of data in the database processing,Interaction.And discusses the management method of cable support bridge.Taking the Anqing Changjiang River Highway Bridge as an example,the monitoring of vehicle load,environmental load and other important load sources,through the vehicle load and traffic flow,wind speed and air temperature and humidity changes monitoring,to obtain the bridge structure of the force analysis The required parameters.When the vehicle detection overrun situation occurs,the system can be informed in time,and in the man-machine interface to send the corresponding alarm information.At the same time the system in time to obtain all the vehicle license plate identification information,the formation of overrun vehicle information to save,in the bridge vehicle number plate to extract the overloaded vehicle number plate and save records.At last,the author summarizes the management methods of highway bridges and puts forward the prospect of the next research.
