| 摘 要： | 海底沉船是水下文化遗产的一种重要类型和存在形式,利用综合地球物理手段对福建平潭、莆田及福州海域的海底沉船进行了探测研究,并重点探讨了不同浅地层剖面系统及不同探测频率在不同埋藏状态的水下文物调查中的应用。结果表明:浅地层剖面探测能够有效识别处于不同埋藏状态的沉船,尤其对探测埋藏海底面以下的沉船具有其他探测手段无法比拟的优势,但是探测频率的调节对目标物探测结果存在较大差异,对于埋藏式的海底沉船低频信号探测效果较理想。

| Abstract: | The underwater shipwrecks are an important type and existent form of underwater cultural heritage. Research of the seabed sunken ships in Pingtan, Putian and Fuzhou of Fujian Province is conducted by the combining method of several geophysical techniques, including sub-bottom profiling, side-scan sonar and multi-beam sounding. This paper focuses on the discussion of the application of different types of sub-bottom profiler with different operating frequency bands in the investigation of underwater cultural heritage under different burial conditions. The results show that the sub-bottom profilers can detect the shipwrecks of different burial conditions, including the shipwrecks buried by sediments. Furthermore, the adjustment of the operating frequency has a critical impact on the detection results. According to work we conducted in the study area, it is recommended to choose the low-frequency end signal of the sub-bottom profilers for the detection of buried shipwrecks under the sea. |
