Abstract

The present invention relates to an apparatus and method for measuring the deformation of a concrete structure by using mutual inductance coil matrixes. The method includes the following steps that: a plurality of sets of three-dimensional matrix one-transmitting & multi-receiving electromagnetic detection coil groups are uniformly pre-buried in the concrete structure; and the change of the relative distances of electromagnetic detection transmitting coils and electromagnetic detection receiving coils is monitored, so that the deformation amount of the concrete structure can be measured indirectly, and the deformation stress distribution condition of the concrete structure is deduced; and therefore, real-time monitoring of the deformation of the concrete structure can be realized, potential security risks can be predicted, so that preventive measures can be taken, and thus, the occurrence of dangerous accidents can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of structural health monitoring, in particular to a device and method for measuring deformation of concrete structures. Background technique [0002] Structural health monitoring is an emerging discipline, which refers to the implementation of damage detection and identification of engineering structures, and its application fields range from aircraft engines to bridges, tunnels, and large buildings. Among them, concrete structures will inevitably be damaged due to various natural factors or human factors during long-term use, such as environmental changes, component degradation, fatigue corrosion, and structural deterioration or decline in stiffness and strength. Factors that affect the safety and use of structures. At present, engineering accidents occur frequently in our country, such as sudden breakage of bridge concrete structure and sudden collapse of buildings, etc., which have caused heavy casualtie...
