高分辨率的声波探测在浅海工程中的应用

APPLICATION OF THE HIGH-RESOLUTION ACOUSTIC SURVEY TO OFFSHORE ENGINEERING

利用高分辨率的回声测深仪、旁侧扫描声纳和浅地层剖面仪对海底进行探测,可获得调查区水深、底形及底床下浅层沉积物结构等信息。通过解译分析可绘制出进行浅海工程场地评价所需的海底地形图、地貌图、浅地层剖面图和等厚度图等一系列图件,从而可为浅海工程的设计、实施以及日后防护提供依据和保证。本文以1989年所进行的浅海石油钻井平台的井位优选为例,说明高分辨率的声探在浅海工程中的重要作用。

Using high-resolution echo-sounder,side scan sonar and subbottom profiler to survey the seafloor,We have obtained a lot of data about water depth,topo- graphy,morphology and the shallow stratigraphic texture of the survey area. After interpretation and analysis,we can draw a series of maps as bathymetry, topographical map,geomorphological map.Subbottom section map and isopach map that needed by the offshore site evaluation.Thus they can give security to the design,performance and the protection in the future of the construction in the shallow area.This paper shows that high-resolution acoustic survey plays an important roles in the marine engineering through the offshore site evoluation in 1989.
