Method and system for detecting wall shape variation and building

Abstract

Provided is a method for detecting wall shape variation. The method comprises the steps that at least two sensor elements and an optical fiber tension adjusting device are arranged on the upper portion of a main structure of a building to be monitored to form testing points; a building model is built according to the building to be monitored, and the testing points are connected with the built building model through an optical fiber server; the attribute variation of the arranged sensor elements is analyzed according to the optical fiber sever to obtain corresponding optical variable data, and the tension strength of all testing points on the main structure of the building to be monitored is calculated; the variation of the calculated tension strength of each testing point is analyzed, and variation corresponding to a wall shape is described on the building model according to a analysis result. According to the method for detecting wall shape variation, a sensing technology is used, trace distorted split information on a wall is detected and analyzed, the hidden danger of the building is output quickly and flexibly, and the problem that early warning of deformation hidden dangers is difficult to give out to an existing large-scale building reinforced wall structure is solved. In addition, the invention further provides a system for detecting wall shape variation and the building.

Description

technical field

[0001] The invention relates to safety detection technology, in particular to a method and system for detecting changes in the shape of a wall and a building thereof. Background technique

[0002] In reality, many large buildings, such as large reservoir dams, large office buildings, expressway overpasses and multi-storey overpasses in urban areas, etc., have strict national standards for quality control during the construction process, and Before these buildings are put into use, they will undergo strict quality inspection and inspection, and they can be put into use after passing the test. However, once these buildings are put into use, the main structure of the building is often caused by non-human damage factors such as natural disasters and sudden changes in external forces during use, such as the change of the bearing capacity of the main structure of the bridge due to continuous rain and water loss. Deformation of a certain main structure; due to the ...
