一、块状散体摩擦角的研究散体內摩擦角是散体主要力学参数之一,它表示了散体的剪切强度。在水利工程设计、道路工程设计、矿山工程设计以及装载、运输、储存、破碎等设备设计时,是不可缺少的原始数据。对细粒散体(如砂、土)的内摩擦角,国内外科技工作者进行了广泛深入的实验研究,但对块状散体的内摩擦角,实验研究还不多,结论也不完全一致。本文根据我们自己的实验数据,并对有关资料进行分析,对块状散体内摩擦角的确定以及主要影响因素提出以下观点。
First, the study of bulk friction angle The bulk friction angle is one of the main mechanical parameters of the bulk, which indicates the shear strength of the bulk. In the hydraulic engineering design, road engineering design, mining engineering design and loading, transportation, storage, crushing and other equipment design, is indispensable raw data. For the internal friction angle of fine granular dispersions (such as sand and soil), domestic and foreign scientists carried out a wide range of in-depth experimental studies, but the bulk friction of the bulk angle, experimental study is not much, the conclusion is not complete Consistent. Based on our own experimental data and analysis of relevant data, the paper puts forward the following views on the determination of the internal friction angle and the main influencing factors.
