中文摘要:
      利用全覆盖的多波束测深、侧扫声纳和浅地层剖面等声波探测数据,分析研究了青岛近海灾害地质类型及其声学反射特征,编制了青岛近海灾害地质图。青岛近海灾害地质主要有:活动断层、潮流沙脊、活动沙波、海底滑坡、出露基岩、礁石、埋藏断层、侵蚀沟槽、潮流三角洲和埋藏古河道等。根据其危害程度和成因对该海域的灾害地质类型进行了分类,并对其形态特征、空间分布、成因机制及对海洋工程建设的影响进行了分析讨论。结合前人研究成果,探讨了构造运动、海平面变化和现代水动力等地质环境因素对青岛近海灾害地质形成和分布的影响。通过对青岛近海灾害地质研究,可为该地区海洋工程建设和防灾减灾提供理论基础。
英文摘要:
      Based on the acoustic data, including multi-beam echo sounding, side scan sonar and sub-bottom profile, the types and acoustic reflection features of hazardous geology in Qingdao offshore are analyzed and studied. The hazardous geology map of Qingdao offshore is compiled. The types of hazardous geology in Qingdao offshore include active faults, tidal sand ridges, active sand waves, submarine landslide, exposure bedrocks and reefs, buried faults, eroded gutters, tidal deltas, buried paleochannels and so on. According to their danger level and formation, the hazardous geology types are classified. Hazardous geology's shape characteristics, distribution, formation mechanism and effects on marine engineering building are analyzed and discussed. Based on previous research products, this paper discusses geologic environment factors, including tectonic movement, sea -level change and modern hydrodynamics, which affect hazardous geology's formation and distribution in Qingdao offshore. Study on hazardous geology in Qingdao offshore will provide a basis for marine engineering construction, disaster prevention and mitigation in this area.
