Applications of Acoustic Positioning Technique in Construction of the Immersed Tunnels

摘要

This paper aims at the problem of the precise sinking for theoverweight and huge immerse tunnel elements in construction of theundersea tunnels. To avoid application of the measuring tower intraditional construction and reduce the rounds of the diving by divers, amethod based on underwater acoustic positioning technique is proposedin this paper that can reduce the cost and risk of constructioneffectively. Meanwhile, increasing the positioning precision, the keytechniques of the underwater acoustic positioning technique are alsoinvolved. Finally, the paper gives an entire method for sinking theimmerse tunnel elements based on underwater acoustic positioningtechnique and the simulation results show that the algorithm has a goodprecision in positioning the tunnel elements.
