Abstract

This invention disclosed a monitor device used in ocean perambulation and a method. It can be used in measuring acoustics parameters of sediment precisely. It can collect data without altering the sediment and the environment. It has advantages compared with traditional methods. It can be applied to research sound velocity of sediment, sound attenuation, dispersion and reflection character of seabed interface, acoustics geotechnics character of sediment, natural gas hydrate and aeration zone in shallow sea, etc.

Description

technical field [0001] The present invention relates to a monitoring device, in particular to a marine engineering exploration device, and also relates to a monitoring method, in particular to an acoustic in-situ testing method. Background technique [0002] Ocean engineering exploration is to provide necessary and reliable results of seabed topography, seabed rock and soil, and marine environment characteristics for ocean engineering construction by means of measurement, testing, exploration, simulation, and analysis. Marine engineering survey mainly includes three sub-specialties: marine engineering survey, marine geotechnical survey and marine engineering environmental survey. Marine engineering survey includes seabed topographic survey, seabed surface condition side scan and bed stability analysis; marine rock and soil survey includes seabed near-surface sedimentary stratum structure detection, seabed rock and soil engineering (physical, mechanical) properties, etc.; mar...
