辽东湾葵花岛构造区海洋工程地质条件分析

通过对水深、浅地层剖面、侧扫声纳和海底钻探取样等实测资料的详细分析, 揭示了辽东湾葵花岛构造区的自然地质状况和复杂的海洋工程地质环境特征。该海区海底地形地貌虽然较为简单，但沉积物为近代沉积的饱和海相、陆相沉积物，具有含水率高、液化指数高、承载力偏低等特点，并存在海底冲刷深槽、埋藏古河道、浅层气等潜在灾害地质因素，对海上构筑物存在直接或潜在的危险性，应引起高度重视。

Geologic conditions analysis of marine engineering in Kuihua island structural area in Liaodong bay

It is shown from the analysis results of water depth, shallow seismic section, side scan sonar and bottom sample data that the Kuihua island structure of Liaodong bay has advantageous natural geologic conditions and complex marine engineering geologic environmental characteristics. Although the submarine topography is simple, the sediments is saturated modern marine and terrestrial sediments with characteristics of high moisture content, high liquefaction index, low carrying capacity , etc., and there are many hazard factors including submarine deep scour channel, buried ancient river course, shallow gas formation, etc., which will constitute direct or potential hazards to the marine structures. So, much attention shall be paid to these hazard factors and sedimental characteristics.
