泥沙颗粒水下休止角的研究

摘要

泥沙水下休止角反映了泥沙颗粒状之间在一定的介质条件下所发生的静态相互作用.本课题首先从泥沙颗粒水下休止角的基本概念出发,探求其产生的内在机理,并采用概率论方法和力学理论分析水下休止角,最后给出不同理论下水下休止角的表达式.%Sediment particles' angle of repose reflects the static interactions among sediment particles under certain media condition. Hie paper starts from the concept of sediment particles' angle of repose, exposes its mechanism of production, and analyzes angle of repose by using probability theory and mechanical theory, at last, gets the expression of angle of repose under different theories.
