【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。
[Abstract]:The geological types and acoustic reflection characteristics of Qingdao offshore disaster are analyzed and studied by using the sonic sounding data such as full coverage of multi-beam sounding, side-scan sonar and shallow stratum profile. The geological map of Qingdao offshore disaster is compiled. The main geological hazards in Qingdao offshore are active fault, tidal current sand ridge, active sand wave, submarine landslide, outcrop rock, reef, buried fault and erosion trench. According to the damage degree and origin of tidal delta and buried paleochannel, the disaster geological types in this sea area are classified, and their morphological characteristics and spatial distribution are also analyzed. The mechanism of formation and its influence on marine engineering construction are analyzed and discussed. Combined with the previous research results, the tectonic movement is discussed. The influence of geological environmental factors such as sea level change and modern hydrodynamics on the formation and distribution of coastal hazards in Qingdao. It can provide theoretical basis for marine engineering construction and disaster prevention and mitigation in this area.
