海底沉积物声学性质测量技术评述

Measurement techniques of acoustic properties of marine sediments: a review

由于资源勘探、军事应用、岩土特性声学调查和声波传播理论研究等的需要,多年来人们一直在进行海底沉积物声学性质的测量。对海底沉积物声学性质的取样测量技术和原位测量技术进行了叙述,分别总结了两种测量技术存在的问题,认为下一步有必要发展海底沉积物低频声学性质的直接测量技术,建议在原位测量海底沉积物声学性质参数的同时测量其他性质参数以便于对比研究,并设法提高原位测量的工作效率。

Due to the needs of resources exploration, military application, acoustic survey of geotechnical characteris- tics, research on acoustic wave propagation theory etc, the measurements of acoustic properties of marine sediments have been conducted for years. The sampling measurement technique and in-situ measurement technique of acoustic properties of marine sediments are reviewed herein, and the problems of the two measurement techniques above are summarized respectively. It is considered that developing the direct measurement techniques for acoustic properties of marine sediments at low frequencies is necessary next. To facilitate the contrastive study of acoustic properties and other properties of marine sediments, it is suggested that the measurements of other properties as well as acoustic properties of marine sediments in situ should be conducted. The in-situ measurement＇s efficiency should also be im- proved.
