Bridge Monitoring
According to Rosstat, there are over 42 thousand bridges in the Russian Federation, their total length exceeds 20 thousand kilometers. The importance of bridge structures is enormous. But in the course of use, these technical structures experience a variety of impacts, including non-design loads, and rust.
In addition, it is not uncommon for a road bridge to deviate from the standards established by the design documentation after some time after commissioning. The structural elements of the bridge are deformed, which means there is a risk of premature destruction of the building. Emergency situations can be prevented by assessing and monitoring the technical condition of the bridge at various stages (construction, operation).
The bridge monitoring process includes an assessment of its technical components, which is carried out using geodetic measurements and other studies. Assessment of the condition of the highway bridge allows:
- identify critical changes;
- monitor the technical condition;
- optimize the costs associated with routine maintenance;
- minimize the possibility of structural collapse;
- to give a forecast assessment of the possible dynamics of the technical condition of the structure;
- identify technical defects, cracks, and dislocations;
- give an assessment of how strenuously the supporting components of the structure react.
The purpose of monitoring is to monitor the compliance of the facility‘s condition with the parameters established by the design (engineering) and (or) regulatory and technical documentation.
What types of controls are used
A popular method of assessing the condition of a road bridge is a technical inspection of structural elements through regular non–destructive testing with appropriate geodetic measurements. However, such a periodic assessment of the technical condition of the bridge is not able to take into account the legend of the effect of loads (range and time interval), which is one of the key factors for assessing the remaining life of the bridge.
Therefore, the optimal method for assessing the technical condition of an object is to install a special system for continuous monitoring, to which measuring devices are connected. A similar monitoring system is used for real–time assessment and monitoring of bridge operating conditions and behavior using sensors.:
- inclinometers used to estimate the size of the bridge angle (devices are mounted on supports);
- meteorological station for monitoring weather changes in the area of the bridge location;
- temperature and vibration sensors for monitoring the dynamics of temperature values in the area of finding the bridge and fixing vibrations;
- acoustic emission transducers for recording points of damage;
- video monitoring cameras for video recording of deviations in the condition of a technical facility;
- load cells for assessing how strenuously parts of the structure react.
In addition, it is possible to monitor the condition of the bridge structure not technically, but by examining the bridge components or ground-based laser scanning.
The principle of operation of bridge control systems
During the inspection of the technical components of the facilities, water leaks, damages and other defects in the condition of the structure are detected and the parameters of the detected inconsistencies are measured. You can estimate the thickness of the rust, the width and length of the cracks.
During ground-based laser scanning, the geometric characteristics of the road bridge components are also monitored to assess the shape of the mating components and outlines.
With automatic monitoring, information from sensors is collected on high-performance, ultra-reliable server equipment that can be deployed both on the cloud platform and on the client‘s IT infrastructure with software focused on analyzing large traffic of technical information from measuring instruments.
The server-side analytics modules perform spectral signal processing and auto-calculation of the key shapes of the bridge‘s oscillatory contours. Based on the data obtained on the technical condition of the structure, various graphs can be compiled for evaluation, as well as stress distribution maps, according to which the most dangerous point of the road bridge can be determined.
The Integrated Monitoring Systems Scientific and Technical Center, founded in 2016, has already been able to become one of the leading companies in the market of automotive traffic assessment and control systems (ASMDS) and integrated monitoring systems (SMICS, SMIS) as part of smart transport complexes (ITS).
