本文在概述苏浙沪及邻区海陆地壳结构等研究成果的基础上,利用重力资料及其延拓处理反演该区深部构造轮廓,推断了深断裂的分布和类型;探讨了深部地质构造的特征、区划及其与本区地震活动性的关系,如震源深度的分布,地震分布的区域性和成带性。利用重力均衡理论探讨了茅山地区、郯庐断裂带、南黄海、杭嘉湖等区域的重力均衡状态和构造活动性的关系,从深部构造角度分析了浙江核电站邻近区域地质的稳定性和建厂的可行性。
Based on the research results of the sea-land crustal structure in Jiangsu, Zhejiang, Shanghai and its adjacent areas, the paper uses the gravity data and its extension processing to retrieve the deep structure contours of the area, and deduces the distribution and types of deep faults. Characteristics, zoning and its relationship with the seismicity in this area, such as the distribution of focal depth, the regional distribution of seismicity and zonality. The relationship between the gravity balance and the tectonic activity in Maoshan area, Tanlu fault zone, South Yellow Sea, Hangjiahu and other regions is discussed by using the theory of gravity balance. The geological stability and construction feasibility of the adjacent area of Zhejiang Nuclear Power Station are analyzed from the perspective of deep structure Sex.
