摘　　要：本文通过对目前大量海损事故的统计分析,认为搁浅、触礁事故的比例远远大于其他事故,由此造成的损失除了本船外,尚涉及海洋环境的污染等。虽然,水面导航定位设备已臻完善,但水下导航设备的研究进展相当缓慢,这是搁浅、触礁事故的比例近40年来一直踞高不下的重要原因。它已引起航海界的严重关注。通过对超前防浅避礁声纳系统的探讨,提出了一个比较简单的、适合船舶避礁的水下探测设备方案,以求引起航海界和水声同行的重视,共同研究水下导航新设备,减少船舶(特别是超大型船舶)搁浅、触礁事故的发生。According to statistics, the strand and strike accidents, making up about 25% of marine accidents, cause far more ship losses than other marine accidents, which lead to the pollution of the sea and ocean environment. The situation is grim, but the development of the underwater navigation aid seems slow. This paper makes a study of a new aid——the lead avoid strand and strike sonar (LASASS). LASASS takes sounding from a ship to the front underwater rock and thus provides ships with a way to avoid strand and strike accidents.
