Research on Nondestructive Testing Signal of Beam-Slab Wharf Pile Foundation

摘要

Piles foundation of beam-slab wharf is deeply buried in soil and the top of pile is constrained by the superstructure. The detection of pile foundation of beam slab wharf is concealed and complex. First, the finite element model of pile foundation of beam-slab wharf is established, and LS-DYNA is used to simulate the actual nondestructive testing of pile foundation of wharf. Then, deconvolution is used to filter the interference signal in the original signal. Based on the post-processing signal, the integrity of the reinforced pile cap wharf pile can be obtained effectively. According to the above methods, different excitation methods and signal processing methods are used to analyze the pile foundation of beam slab wharf with constraint pile cap, which provides theoretical guidance for practical engineering.
