Embodiment Construction

[0025] The present invention will be further described below in conjunction with drawings and embodiments.

[0026] The present invention is a comprehensive application of multiple physical mechanisms such as electromagnetic mutual inductance, spiral parallel transmission line TDR effect or inductance effect, gravity inclinometer, magnetoresistance effect, etc., and proposes an integrated sensor unit that realizes the aforementioned multiple physical effects. The mutual inductance voltage Uout between two integrated sensors, the stretching amount L of the helical parallel transmission line, the inclination angle θ, and the inclined geomagnetic azimuth angle, and then through theoretical proof and experimental verification, the relationship between Uout, L, θ and the underground horizontal deformation X, vertical deformation The relationship model of Y, on the basis of obtaining X, Y and deformation azimuth, is unified with the measured GPS space coordinates to realize the three...

Abstract

The invention discloses a three-dimensional measuring method and measuring system for underground deformation. The measuring system comprises an in-site measurement instrument and a remote measurement instrument, which are communicated with each other through wireless sensing communication; the in-site measurement instrument consists of an underground deformation integrated sensor string and an underground deformation measurement centralized processing device; the remote measurement instrument consists of a remote receiving device and a PC (personal computer) upper computer; and one end of the remote receiving device is connected with an antenna, and the other end of the remote receiving device is connected with the PC upper computer. The three-dimensional measuring method and the measuring system can realize the three-dimensional measurement of deformations caused by various below-surface reasons and realize the continuous three-dimensional measurement of the underground deformation, which can not be realized by other existing methods; thus the measuring system can possibly become an instrument used for observing the deformation situation of crust deep parts during plate jamming and provide observation data for the mechanism study of the occurrence of earthquake; and measuring instruments for the observation of geological environments in the research of craton destruction and shale gas development are also realized.

Description

technical field [0001] The invention relates to an underground deformation measurement method and device, in particular to a three-dimensional measurement method and a measurement system for underground deformation. Background technique [0002] Observing and studying the deformation and movement of large tectonic plates is an important process for analyzing the relationship between crustal movement and earthquakes. Facts show that there is an inevitable connection between crustal movement and earthquakes. One of the methods is to study the crustal movement and deformation process related to the generation of strong earthquakes through the observation of crustal deformation. Therefore, this kind of observation and research on the deformation of the terrestrial plate is helpful for human beings to understand the movement law of the earth's crust, observe the three-dimensional changes below the ground, provide scientific instruments for the research in the fields of earthquake...
