摘　　要：通过野外地质调查和地震资料解释,重点讨论了三合场、莲花山、张家坪构造的构造模式。龙门山南段浅层发育的构造样式主要为挤压构造样式和压扭构造样式;三合场、莲花山、张家坪构造均为由主断层及其2侧的分支断裂组成的似花状构造,其主断裂具压扭性质。This article discusses the structural pattern of Sanhechang,Lianhuashan,Zhangjiaping Structures in the front of Longmen Mountain in detail through geological survey,seismic data interpretation.The results show that the tectonic style in the south section of Longmen Mountain is mainly compressive tectonic style and compressive shear tectonic style; Sanhechang Tectonics,Lianhuashan Tectonics and Zangjiaping Tectonics are all flower-like structure that consists of the main fault and its branches,the main fault is compressive and sheared.
