| 摘 要： | 应用Klein-510型(美)海底剖面仪装置，把220V AC或24V DC电源能转化为3．5KHZ的超短波向海底发射，经过不同物性的地层所产生的不同穿透与反射效应。从而在返回的信息记录中获得不同的屏谱记录．应用这一原理所获的地层信息可供分析各地层的各种参数如深度、层厚、风化程度和组成物等，如遇到突然异常物如礁石、沉船、断裂带也可从屏谱中显示出来并准确地找到它的位置和尺度。本装置已在厦门湾、湄洲湾、东山湾等多处工程应用中经过实践检验。并获得成功，八尺门海峡的探研同样取得海底地层特征的良好结果。

| Abstract: | Research experiments have been conducted on the acoustic effects of different sedimentary layers of the estuary and bay areas with Klein-510 type subbotton profiler. Clear and continuing sediment layer boundaries have been recorded and compared with drilling cores to reveal the changes of sedimentaty environments. It is found that the weathering index of rock is control by the fault lineand this is an important instrument for all the sea bottom engineerings. |
