Embodiment Construction

[0039] A method for monitoring deformation of an underground cavern, comprising the following measurement process:

[0040] Select the point to be measured and a number of reference points whose positions are known in the underground cavern, measure the distance between the point to be measured and each reference point with a laser, and obtain the coordinates of the point to be measured from the distance between the point to be measured and each reference point, and obtain the coordinates of the point to be measured by The coordinate change of the point to be measured is calculated to obtain the deformation of the underground cavern. The points to be measured are selected according to the requirements, and where the deformation needs to be monitored, choose that place. If the overall deformation of the underground cavern needs to be monitored, a representative area needs to be selected according to the specific conditions of the underground cavern.

[0041] The above measureme...

Abstract

The invention relates to the technical field of measurement of target position data by applying electromagnetic wave reflection except radio waves, and discloses an underground cavern deformation monitoring method and system, and the method comprises the following measurement processes: selecting a to-be-measured point and a plurality of reference points with known positions in an underground cavern, measuring the distance between the to-be-measured point and each reference point through laser, calculating coordinates of the to-be-measured point according to the distance between the to-be-measured point and each reference point, and calculating deformation of the underground cavern according to coordinate changes of the to-be-measured point. According to the invention, the coordinates of the to-be-measured point are calculated according to the distance between the to-be-measured point and each reference point, and full-automatic operation can be carried out after the device is installed; the space position coordinates of the to-be-measured point are calculated by adopting a four-node three-dimensional space positioning method, only one group of real solutions are calculated each time, manual judgment is not needed, and the calculation process can be fully automatically carried out; and no rotating part is arranged, the problem that the rotating part is greatly influenced by vibration is solved, and the device can be used for occasions with obvious vibration.

Description

technical field [0001] The invention relates to the technical field of measuring target position data using electromagnetic wave reflection other than radio waves, in particular to a method and system for monitoring deformation of underground caverns. Background technique [0002] During and after the construction of underground caverns, a certain degree of deformation will inevitably occur, and the deformation is mainly due to settlement deformation. Therefore, during the construction and operation of underground caverns, the monitoring of their deformation plays an important role in ensuring the safety of underground caverns. [0003] At present, there are various methods for measuring the deformation of underground caverns, including a variety of manual and automatic measurement methods, but various manual measurement methods are still the main method. The measurement accuracy of the manual measurement method is limited by the professional level and working methods of th...
