Dimensional Imaging Sonar Damage Identification Technology Research On Sea-Crossing Bridge Main Pier Pile Foundations

摘要

Sea-crossing bridge mostly in deep water rapids turbid waters, underwater photography traditional imaging techniques can not detect damage identification, there is no specific bridge main pier foundation damage identification technology, thus maintenance management department can not grasp the main bridge pier foundation damage situation, there is a big security risk. The present studies on a variety of underwater detection technology comparison analysis of this situation, according to bridge main pier infrastructure characteristics, proposed for main pier foundation bridge damage identification new technology based on three-dimensional imaging sonar.
