Description

LAY-OUT DEVICES FOR FABRICATING A MAGNETIC FIELD IN A
SLIDING MASS
BACKGROUND OF THE INVENTION
I. Field of the Invention [0001] The invention relates to the field of landslide monitoring, and particularly to devices for laying out prefabricated magnetic field in a sliding mass and methods of detecting internal deformation of the sliding mass.

2. Description of Related Art [0002] Landslide monitoring plays an important role in the prevention of landslide disaster. Landslide deformation in depth is an important object of the landslide monitoring, and it is also an important basis for establishing the relationship between internal failure characteristics and the deformation of landslides, recognizing landslide evolution stages, and preventing and controlling landslides.

[0003] There are many monitoring methods for the landslide deformation in depth, mainly including optical fiber sensing technology, TDR, Gayle displacement meter and inclinometer technology. Optical fiber sensing technology, such as pure fiber BOTDR and fiber Bragg grating (FBG), is widely used in experiments at present. However, there are still some problems, such as poor anti-interference and small measurement range. TDR has the advantages of short monitoring time, remote sensing, high safety and high efficiency, but it is very easy to be cut and its reliability is low. The Gayle displacement meter has many advantages, but it's insensitive due to the limitation of setting modes and hypothesis models. The inclinometer technology is widely recognized and most widely used in the landslide deformation monitoring method for its high accuracy and good reliability. In addition, China Three Gorges University has proposed several monitoring methods of landslide deformation in depth based on magnetic positioning, which lack the consideration that the underground environment Date Recue/Date Received 2022-10-17 would affect the power supply of the magnetic positioning sensor after the deformation of landslides.

[0004] The monitoring results of the displacement in depth in practical engineering are unsatisfactory, mainly reflecting in two aspects. Firstly, there is a difference in the stiffness between the engineering implant structure and the sliding mass. A large error would have been generated while the slope displacement is transferred to the measuring instrument, which reduces the accuracy of the deep displacement monitoring results. Secondly, after the sliding mass deforms greatly, the engineering implant structure is often damaged in advance, which results in the failure of time-sharing measurement instruments to be put in the borehole or the damage of the probe of the fixed monitoring instrument. It cannot guarantee the continuity in monitoring the multi-staged evolution of landslides. The deformation coupling between the sliding mass and the monitoring structure of engineering implantation is a key problem that needs to be solved urgently in the current monitoring of displacement in depth.
