摘　　要：通过精细构造解释,在桩海地区识别出北西向、近南北向、北东向和北东东向4组断裂带,垂向上发育深、中、浅3套断裂系统:底部中古生界北北西向逆断裂系统,中部孔店组—沙二段在逆断层前锋位置发育北北东或近南北向正断层,浅部新近系东西向断层下降盘发育大量北东东向断层。构造演化研究认为,桩海地区经历了5次大规模构造运动,断裂演化可以分为8个阶段。Fine structural interpretation has recognized 4 fault zones which are in NW,near NS,NE and NEE trending in Zhuanghai area.Vertically there had developed 3 fault systems,which are mid-Paleozoic NNW reverse fault system at bottom,NNE or near NS normal fault system in the front of the reverse fault of Kongdian-Es2 formation in the middle,and a multitude of NEE faults on the downthrown side of the Neogene fault in the shallow formation.Structural evolution study shows that Zhuanghai area had experienced 5 large-scale tectonic movements and 8 stages of fracture evolution.
