The construction quality of bridges directly affects their safety and service life.Prefabricated piles are one of the key components in bridge construction.To ensure construction quality,reliable quality inspections of prefabricated piles are necessary.Starting from the non-destructive testing of mechanical cracks in prefabricated piles,this paper elaborates on the working principles,advantages and disadvantages,and specific applications of several non-destructive testing technologies,aiming to provide theoretical support for improving the quality of bridge construction.
