中文摘要：
在运用Miall的建筑结构分析法定义了辨状河砂体6级界面的基础上，通过水动力成因分析等方法在砂砾质、砂质辨状河心滩中识别出心滩充填（CB）、顺流加积底形（DA）、心滩尾缘（CBL）、落於层（FS）和泛滥平原泥（FF）等5种结构要素（其中心滩尾缘是尝试性初次提出），并建立了心滩沉积模式和4种单井心滩结构要素组合模式。
英文摘要：
Based on the six - level interfaces of the braided river sand body, which was defined by the architectural ele- ment analysis of Miall, in gravel and sand braided river channel bar, hydrodynamic factors were used to identify five types of structural elements which include channel bar fill （ CB）, downstream substructure aggradation （ DA）, channel bar trai- ling edge （CBL）, drop in the layer （FS） and flood plain mud （FF）. Among these structural elements, CBL was first pro- posed. Finally, the channel bar deposition mode and four types of combination model of channel bar structure elements of single well were established.
