一、概述 浅地层剖面仪是一种走航式声学探测设备,它能够在施测的同时连续地绘制出一套工作船下方的海水深度及海底以下数十米之内的地质剖面图象。如配合一定数量的钻探、土工试验,经过内业分析、整理,最终还可提出一套各探测线下部的连续的工程地质剖面图,供规划、可行性研究或设计人员使用。这种设备在发达的工业国家中已被广泛地应用于石油勘察、海底电缆敷设、筑港及航道疏浚等工程中。七十年代中期,我国研制成功的这种设备在渤海、东海、黄海、南海等海域的13个港口、航道、海岸带调查和
I. Introduction The shallow stratum profiler is a navigational acoustic detection equipment that can continuously draw a set of seawater depth below the workboat and the geological cross-section within a few tens of meters below the seafloor while measuring. For example, with a certain amount of drilling and geotechnical tests, after the analysis and arrangement of domestic industries, a set of continuous engineering geological profiles of the lower part of each exploration line can be proposed finally for use by planning, feasibility studies or designers. Such equipment has been widely used in petroleum exploration, submarine cable laying, port construction and waterway dredging in the developed industrialized countries. In the mid-1970s, China successfully developed such equipment in the Bohai Sea, the East China Sea, the Yellow Sea, the South China Sea and other 13 ports, waterways, coastal survey and
