本文根据苏、浙、沪近期水准复测资料,编制了长江三角洲及邻近地区垂直形变图。结合有关资料分析研究了该区垂直形变与地质构造关系。认为现代地壳垂直形变继承性升降明显,垂直形变与主要断裂活动有一定关系,与第四系沉积厚度和工业抽用地下水过量关系密切。
Based on the data of the recent level survey of Jiangsu, Zhejiang and Shanghai, this article has prepared the vertical deformation maps of the Yangtze River Delta and its adjacent areas. Combined with the relevant data analysis of the vertical deformation and the relationship between the geological structure. It is considered that the succession and fall of vertical crustal deformation of modern crust are obvious, and the vertical deformation has a certain relationship with the main fault activity, which is closely related to the sedimentary thickness of Quaternary system and the over-pumping of industrial pumping groundwater.
