| 摘 要： | 为开展琼州海峡跨海通道地壳稳定性评价,利用Sonar Beam S-150D侧扫声纳系统在琼州海峡海底开展了地形地貌调查,获得了琼州海峡跨海通道工程区的侧扫声纳影像。通过数据分析、图像判读,分析了地质灾害类型及其可能的危害。在琼州海峡海底发现软土、活动沙波、岸坡及活动构造等微地貌单元,跨海通道工程施工、运行阶段都将遭受相关地质灾害的危害。这些资料和分析为跨海通道工程地壳稳定性评价提供了基础资料,为工程规划线路优选、建设实施提供了技术支撑。研究表明侧扫声纳技术可应用于海底地壳稳定性调查与评价工作中。

| Abstract: | For the crustal stability assessment of cross-sea channel of the Qiongzhou Strait, the Sonar Beam S-150d scan sonar system was applied to the topography investigation of the seabed in Qiongzhou Strait, in which the side scan sonar image of the engineering region was obtained. Through data analysis and image interpretation, the types of geological hazards and their potential harm were analyzed. Microgeomorphic units including soft ground, movable sand wave, bank slope and active tectonics are found on the Qiongzhou Strait seabed, which will cause relative geological disasters in the construction and operation stage of cross-sea channel engineering. All the data and analysis provide basic information for the crustal stability assessment of cross-sea channel engineering and technical support for the optimization of engineering planning and implementation. It shows that the side scan sonar technique can be applied to the investigation and assessment of the stability of the submarine crust. |
