摘　　要：This article takes the inspection and appraisal of a certain migratory wooden structure as the backdrop, presents the inspection process of the wooden structure. Upon on-site examination, it was discovered that the connection (or node) construction mode of the building was correct. Only local surface flaws were present, and the operation was normal. The stress wave velocity of the randomly inspected wooden columns with surface cracking was close to the critical velocity, suggesting that no obvious cavities or decay defects existed within the measured wooden components. Based on the inspection outcomes, finite element computations were carried out for the wooden structure, arriving at the conclusion that the maximum stress value of the wooden members was smaller than the designed value of wood strength, and the vertical bearing capacity conformed to the requirements of the specifications. And rationally offered relevant treatment suggestions, providing a reference for the inspection and identification of such projects.This article takes the inspection and appraisal of a certain migratory wooden structure as the backdrop, presents the inspection process of the wooden structure.
