泥沙颗粒水下休止角与内摩擦角差异化初步探索
Preliminary exploration of difference between submarine angle of repose and internal friction angle of sediment particles
摘要
Abstract
The contradiction between slidable incipient model and rolling incipient model is obtained based on the relevant researches of incipient motion and submarine angle of repose. The doubt about the most basic understanding , which is " the submarine angle of repose is equal to the internal friction angle associated with sediment particles" , is put forward. The research shows the submarine angle of repose is less than the internal friction angle of sediment particles via the physical experiments on submarine angle of repose and internal friction angle associated with sediment particles.关键词
