A method for overall health monitoring of road and bridge

Abstract

The invention discloses a road-and-bridge overall health monitoring method and belongs to the road-and-bridge structure monitoring field. The road-and-bridge overall health monitoring method comprises the following steps of S101, arranging an angle reflector nearby a railway bridge; S102, integrating a geographic position receiver on the angle reflector; S103, using a satellite-borne SAR to acquire settlement data of the railway bridge; S201, laying a foundation SAR nearby the railway bridge and using the foundation SAR to acquire real-time deflection data of the railway bridge; and S301, fusing the data acquired by the satellite-borne SAR and the foundation SAR and forming a monitoring analysis report. In the prior art, the road-and-bridge overall health monitoring analysis method can not effectively use collected data information. In order to solve the above problem in the prior art, the invention provides the road-and-bridge overall health monitoring method and the corresponding road-and-bridge overall health monitoring analysis method is provided.

Description

technical field [0001] The invention relates to the field of road and bridge structure monitoring, and more specifically relates to a method for monitoring the overall health of road and bridges, and is especially suitable for the overall health monitoring of railway bridges. Background technique [0002] In recent years, with the sustained and rapid development of my country's national economy, my country has launched the construction of a number of high-speed railways (passenger dedicated lines). The emergence of high-speed railways has brought new requirements and challenges to the design, construction, monitoring and maintenance of traditional railways. In order to ensure the normal operation of the high-speed railway, the high-speed railway has very high requirements for the monitoring of railway settlement and track deformation. Therefore, it is particularly important to do a good job in monitoring the health of high-speed railways. [0003] At present, the monitorin...

Problems solved by technology

This method is simple in technology, easy to operate, and high in monitoring accuracy, but it also has the following obvious shortcomings: (1) It requires a lot of manpower and material resources; (2) Equipment measurement is easily affected by bad weather; (3) For special modes (such as Closed interchange mode) high-speed rail can only be measured when the high-speed rail is out of service, and the work efficiency is low; (4) it is difficult to carry out long-term large-scale high-speed rail monitoring

However, the disadvantage of this application is that the application lacks a specific analysis method for the settlement monitoring results of high-speed rail structures, making it impossible to effectively use the collected high-speed rail structure settlement information

[0006] To sum up, there is a lack of an overall health monitoring and analysis method for roads and bridges that can effectively utilize the collected data information in the prior art. To solve this problem, proposing corresponding solutions is a technical problem that needs to be solved urgently in the prior art.
