Research on Concrete Damage Detection Based on Electrical Resistivity Tomography Technology

Chuan Yu


Nondestructive detection technology of concrete structure building is of great importance to ensure the safety and durability of structures. As an emerging industrial nondestructive testing technology, resistivity tomography has a broad application prospect in the damage detection of concrete structures. Based on the resistivity tomography and its physical theory, this paper uses the fully embedded electrode design and the four-electrode measurement method for imaging detection of crack damage, and verifies the reliability and feasibility of the experiment design by virtue of analogue simulation software, and carries out objective evaluation and comparison with the quality of detection images through combination with the image evaluation indexes. The test results indicate that this method can be applied to the nondestructive detection of concrete structures.
