摘要
本文再现了水下扇的形成及演变过程,剖析了水下扇沙体的平面展布特征、沙泥组合特征、沉积层序及水动力机制,并建立了水下扇的沉积相模式。另外,通过人造波浪模拟了湖滩的形成。
This paper presents the process of formation and evolution of a subaqueous fan,analyzes the features of distribution and sand-mud assemblage,sedimentary sequence and hydrodynamic mechanism of the subaqueous fan sandbody,and constructs the facies model of the subaqueous fan.Besides,the formation of a lake beach sandbody was simulated by using man-made waves.
