Abstract

The invention provides a fiber grating strain sensing mechanism and a method for monitoring the subsidence of a full-space support structure. The fiber grating strain sensing mechanism comprises a fiber grating strain sensing assembly, wherein the first end of the fiber grating strain sensing assembly is connected with a monitored member, the fiber grating strain sensing assembly is connected with a demodulator, and the monitored member is arranged between the foundation and a top template; and a pressure transfer member, wherein the first end of the pressure transfer member is connected with the foundation or the top template, the second end of the pressure transfer member is connected with the second end of the fiber grating strain sensing assembly to transfer the deformation of the top template or the foundation to the fiber grating strain sensing assembly via the pressure transfer member. The method solves a problem incapable of monitoring the real-time subsidence of the full-space support structure in the prior art.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a settlement monitoring method of an optical fiber grating strain sensing mechanism and a supporting structure of a building. Background technique [0002] Support structures (such as full hall support) have been widely used in engineering construction, such as bridge construction, house construction, etc. However, there are many safety hazards in the construction process, and engineering problems caused by the settlement and collapse of supporting structures emerge in endlessly. The existing fully supported structure is mainly to study its material properties and structure. So far, no settlement monitoring method suitable for the supported structure has been proposed, which leads to frequent engineering accidents caused by the settlement and collapse of the supported structure, threatening the work. personal safety of personnel. Contents of the invention [0003] The ...
