摘　　要：通过对连云港南部沿海地区特定的地质环境背景、人类工程活动以及地面沉降现状的分析,阐述了连云港南部沿海地区地面沉降的驱动因素主要有地下水过量开采、工程建设产生的附加荷载、土体自然固结压实、海平面上升四个方面,并初步探讨了各个驱动因素对地面沉降的影响程度。结果表明:地下水过量开采、土体自然固结压实为连云港南部沿海地区地面沉降的主要驱动因素,但控制范围存在区域性差异;工程建设产生的附加荷载和海平面上升是不可忽视的驱动因素。By the analysis of the specific geological environment background,human engineering activities and the status of surface subsidence in southern coastal area of Lianyungang City,this paper elaborates on the main driving factors of surface subsidence,i.e.,the excessive exploitation of groundwater,the increase of surface load,natural consolidation of sediment and the absolute rise of sea level,and then preliminarily discusses the influence degree of each driving factor on surface subsidence.The result shows that the excessive exploitation of groundwater and natural consolidation of sediment are the main driving factors,but the control areas of them are different in different regions;meanwhile the increase of surface load and the absolute rise of sea level are also important driving factors.
