Application of the Electromagnetic Induction Method in the Thickness Detection of the Reinforced Protective Layer of Bridge Pier Columns
In order to improve the accuracy of the detection results of the thickness of reinforced protective layers,this article studies the application of the electromagnetic induction method in the thickness detection of the rein-forced protective layer of bridge pier columns based on a highway bridge project.First,it analyzes the detection principle and process of the electromagnetic induction method.Then,it summarizes the factors affecting detection results such as the electromagnetic properties of concrete materials and the diameter and distribution of steel bars.Fi-nally,it applies it to practical projects,and application results show that the qualified rate of the thickness of the rein-forced protective layer of the 3-1 pier column is 100%.
