随着海洋经济建设的高速发展,特别是沿海建筑、桥梁、风电场等重大工程建设,降低海域灾害地质的风险迫在眉睫。通过以福建省地震风险普查专项在台湾海峡采集的最新高分辨率浅地层剖面数据为依据,结合研究区的历史资料和灾害地质概况,识别了浅层气、麻坑、古河道、潮流沙脊等潜在灾害地质因素,以此绘制了灾害地质平面分布图,同时探讨了在浅地层剖面中识别活动断层的可能性。结果表明:研究区北部的灾害地质因素主要是广泛分布的浅层气,中部主要是活动断层和埋藏古河道,南部主要是分布较广的潮流沙脊活动和频度较高的地震活动。

With the rapid development of marine economic construction, especially the construction of major projects such as buildings,bridges,and wind farms in coastal areas,it is urgent to reduce the risk of geohazards in marine areas. Based on the latest high-resolution sub-bottom profiler data collected in the Taiwan Strait area through the Fujian Province earthquake risk survey,combined with the historical data and geohazard information in the study area,this paper identified potential geohazard factors such as the shallow gas,pockmarks,paleochannels, tidal sand ridges,and so on. On this basis,the horizontal distribution map of geohazards was plotted. Meanwhile, the paper discussed the possibility of identifying active faults in the sub-bottom profile. The results show that the geohazard factors in the northern part of the study area are widely distributed shallow gas. In the middle part,there are mainly active faults and buried paleochannels, and in the southern part, there are mainly widely distributed tidal sand ridges and frequent seismic activities.
