Problems solved by technology

[0003] At present, the deformation monitoring of underground caverns is often carried out on a certain point. This monitoring method cannot reflect the overall deformation of the cavern, and usually there are certain monitoring loopholes.
Moreover, the traditional monitoring method is inefficient and cannot realize automatic data processing. It can only store on-site data and cannot realize remote data reading.

Abstract

The invention discloses a space three-dimensional system for monitoring the deformation of an underground cavern lining for long time. The space three-dimensional system comprises a site end and a remote end, wherein the site end is in communication connection with the remote end; and the site end is installed at the position of an underground three-dimensional cavern. According to the space three-dimensional system, a point mode and a distributed arrangement method are combined, the deformation of the surface of the underground cavern lining can be monitored in all directions, the number of measuring points is large, the measuring precision is high, field and remote data storage can be realized, and through long-term monitoring, a dynamic deformation cambered surface map of the three-dimensional cavern lining can be obtained.

Description

technical field [0001] The invention relates to a space three-dimensional system for long-term monitoring of underground cavern lining deformation, and belongs to the technical field of optical fiber grating sensing. Background technique [0002] Before the underground cavern structure is damaged, it is often accompanied by large deformation. Therefore, all-round monitoring of the deformation of the lining surface in underground caverns has become one of the important means of cavern safety monitoring. [0003] At present, the deformation monitoring of underground caverns is often carried out on a certain point. This monitoring method cannot reflect the overall deformation of the cavern, and usually there are certain monitoring loopholes. Moreover, the traditional monitoring method is inefficient and cannot realize automatic processing of data. It can only store on-site data and cannot realize remote data reading. Contents of the invention [0004] The technical problem ...
