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 applic

Embodiment 1

[0056] combine Figure 1-3 , the overall road and bridge health monitoring method of the present embodiment, comprises the following steps:

[0057] S101: Arrange corner reflectors near the railway bridge, wherein: the corner reflectors are arranged on both sides of the railway bridge, the number of corner reflectors should not be less than 4, and at least 2 corner reflectors are placed on one side of the railing of the railway bridge. The reflector is aligned with the beam direction of the spaceborne SAR;

[0058] S102: Integrating a geographic location receiver on the corner reflector; wherein, the geographic location receiver is a GPS receiver or a Beidou receiver.

[0059] S103: Obtain the settlement data of the railway bridge using spaceborne SAR, wherein: first obtain the SAR image of the railway bridge area, then use the corner reflector to perform interference processing on the acquired SAR image, and use the three-dimensional coordinates of the corner reflector obtai...

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...
