| 摘 要： | 根据地球物理、声学探测、海底取样及实验室测试等实测资料详细分析,发现琼州海峡具有独特的自然条件以及复杂的工程地质特征。海底地形地貌非常复杂,存在沙波、沙堤沙丘、冲刷槽、冲刷脊和丘状突起、陡坡、滑坡、珊瑚礁、浅埋岩石、软弱地层等潜在的地质灾害因素,尤其在琼州海峡中央深槽区,坡度很大,分布着多种潜在的地质灾害,是海底光缆的危险区,应引起重视。

| Abstract: | Based on geophysical prospectings,acoustic survey,core sampling and geotechnical test,it is found that Qiongzhou Strait has special natural conditiongs,complex topographical and geomorphological sea floor features.There are many geological hazard factors such as sand wave,sand barrier,sand dune,scour trough,scour ridge and mound-like protuberance,steep slope,landslip,coral reefs,shallow-buried rock and soft layer,which will bring potential dangers to this area.Especially at the edge of Central trough,the st... |
