Abstract:
A new method is presented for silo classification using the rupture plane in the storage. The proposed method is based on the formula of rupture plane orientation determined by the aspect ratio of specified silos and involves the effects of the conical angle of the storage surface, so it can deal with two cases: the conical angle of the storage surface and the flat storage surface. Compared with the two popular methods based on the silo-aspect ratio and the silo rupture plane, respectively, in current engineering design, the new method can give a range of critical aspect ratios to classify deep silos and squat silos according to the conical angle of the storage surface or the flat storage surface. Moreover, the range covers the critical aspect ratios obtained from the existing classification methods including the Chinese code based on silo aspect ratios, the German code, Reimbert brothers’ definition and Liang et al.’s definition, so it is a more general method to classify silos and the existing methods can be viewed as special cases of the presented method.
提出了一种新的基于破裂面的深浅仓分类方法.该方法考虑了贮料顶面倾角的影响, 可以处理贮料顶面平堆和锥堆2种工况. 以此为依据, 对目前工程设计中常用的2类深浅仓分类方法(即按高径比分类方法和按破裂面分类方法)进行评价. 结果表明: 该新方法能够根据贮料顶面锥堆或平堆给出区分深浅仓高径比的临界值范围, 该范围覆盖中国规范按高径比分类方法、德国规范、Reimbert兄弟、梁传珍等现有方法所给出的区分深浅仓的高径比临界值. 因此, 该方法是一种更一般性的深浅分类方法, 而现有的深浅仓分类方法只是它的特例.
