This procedure is formulated in order to unify the dynamic testing methods and technical requirements for port engineering pile foundations and effectively control the quality of engineering testing. This procedure is applicable to high-strain testing of concrete precast piles, cast-in-place piles, steel piles and composite piles in port projects, as well as low-strain dynamic testing of concrete precast piles and cast-in-place piles. The dynamic inspection of pile foundations of navigation structures and shipbuilding hydraulic structures can be carried out with reference to this.
