FBG Sensing Technology for Rock-soil Deformation Monitoring in the Civil Engineering Industry
Rock-soil deformation is a major concern in civil engineering, as it can lead to serious hazards such as landslides, foundation settlement, and slope failure. Monitoring rock-soil deformation is crucial to ensure the safety and stability of infrastructure projects. In recent years, fiber grating sensing technology has emerged as a promising technique for monitoring rock-soil deformation. In this article, we will discuss the problems that fiber grating sensing technology can solve, and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support the rock-soil deformation monitoring in civil engineering industry.
Fiber Bragg Grating Sensing Principle：
Fiber Bragg gratings (FBGs) are periodic structures that are inscribed in the core of an optical fiber. These structures reflect a specific wavelength of light that is determined by the periodicity of the grating. When the grating is subjected to mechanical or thermal strain, the reflected wavelength changes in a predictable manner. By monitoring the reflected wavelength, changes in strain, temperature, and other parameters can be detected. FBG sensors can be used to monitor a wide range of parameters, including strain, stress, temperature, and vibration.

Hazards of Rock-Soil Deformation in Civil Engineering:
Rock-soil deformation is a significant problem in civil engineering, as it can cause various hazards such as landslides, foundation settlement, and slope failure. Landslides are a common occurrence in mountainous regions and can cause severe damage to infrastructure and loss of life. Foundation settlement can lead to structural damage to buildings and bridges, while slope failure can result in road closures and traffic disruption.
The Challenges in Monitoring Rock-Soil Deformation：
Monitoring rock-soil deformation is challenging due to the complex nature of the geologic environment. The deformation can occur over a wide range of timescales, from seconds to years, and can be influenced by various factors such as temperature, humidity, and water content. Conventional monitoring techniques such as strain gauges and extensometers are limited in their ability to provide accurate and continuous measurements over long periods. Moreover, they are often difficult to install in remote and inaccessible locations.
What Problems Can be Solved by FBG Sensing Technology：
Fiber grating sensing technology provides a non-invasive and non-destructive method of measuring and monitoring the deformation and stress of rock and soil. It can help to overcome some of the challenges of traditional monitoring methods, such as limitations in spatial coverage, accuracy, and sensitivity. With fiber grating sensing technology, civil engineers can accurately and continuously monitor the deformation and stress of rock and soil in real-time, which can help to prevent and mitigate disasters caused by landslides, slope failures, and other geological hazards.
One of the major advantages of fiber grating sensing technology is its ability to provide distributed sensing over long distances. This means that multiple sensors can be installed along a pipeline, slope or underground excavation to monitor deformation and stress at multiple locations. Fiber grating sensing technology can also detect subtle changes in deformation and stress that may not be visible to the naked eye, which can help to identify potential failures before they occur.
Another advantage of fiber grating sensing technology is its high accuracy and precision. The technology is capable of measuring deformation and stress to sub-micron and sub-millimeter accuracy, which is essential in applications where even small changes in deformation and stress can have significant impacts on the safety and stability of infrastructure.
In addition, fiber grating sensing technology is immune to electromagnetic interference, making it suitable for use in harsh environments, such as near high-voltage power lines or in areas with high electromagnetic interference.
Overall, fiber grating sensing technology can help to address some of the key challenges in monitoring rock-soil deformation, including the need for continuous and accurate monitoring over large areas, and the ability to detect subtle changes in deformation and stress.
