摘　　要：在分析形成沉积物重力流所需要的试验条件基础上,利用沉积模拟试验方法,在考虑不同的斜坡长度和坡度,在风暴浪、震动以及波浪冲刷3种触发作用机制下,探讨了形成沉积物重力流的条件及控制因素,阐述了沉积物重力流砂体的分布及演化特征。On the basis of analyzing test conditions of gravity flow of deposits, methods of depositional simulation testing are used to study the conditions and control factors of forming depositional gravity flow for the mechanism of storms, waves, vibration and wave washing in consideration of different lengths and slopes of the deviated slopes. The characteristics of depositional gravity sandbody distribution and evolution are described.
