松散材料作用在仓底和仓壁上的压力的计算

本文讨论了松散物料作用在仓底和仓壁压力的计算方法。首先,在介绍Janssen工程师关于小麦在木仓底载荷的试验资料的基础上,讨论了Janssen、Reimbert和的计算方法,并与试验结果比较。结果表明,Reimbert的方法与实际较接近。这一结论具有重要的参考价值,从以上的比较中,还可以了解到,准确地得到装裁材料在壁上的摩擦系数是非常重要的。最后指出了“压力尖峰”问题

Calculation of Pressures on Silo Bottom and Walls

A discussion is given of the methods for calculation of pressures exerted on the bottom and walls of silos. Starting with Jassen's experimental results about the lood on the base of a timber silo filled with wheat, comparison is made between the calculation methods by Janssen, Konnen, Reimbert and Zenkov, and between the calculated results and experimental ones, to the conclusion that Reimbert's method is of great reference value. Also found through the comparison is the extreme importance of the coefficient of friction of the filling material against the silo walls. The problem of pressure peak is also mentioned
