该文在作者前一篇论文［５］基础上，提出了法压力系数ζｉ依赖于贮料压力特性指数ηｉ、漏斗倾角α、摩擦系数μ的计算公式，及根据漏斗底部压力ｐｖｉｂ确定ηｉ的方法。还通过理论分析和数值比较，评述了现有法压力系数的２种取值方法。文中给出了模型实验的４组ｐｖｉｂ、ηｉ、ζｉ值及２组法向压力测试数据，采用相应ηｉ、ζｉ值按作者公式计算的法向压力与测试数据相近。作者提供的理论、方法及结果，对于筒仓工程设计具有实用性和针对性
On the basis of the author’s previous paper [5], the calculation formula of the law pressure coefficient ζi depends on the storage pressure characteristic index ηi, the funnel inclination angle α, the friction coefficient μ, and the method of determining ηi according to the bottom pressure pvib of the funnel. . Through theoretical analysis and numerical comparison, two methods for determining the existing pressure coefficients are reviewed. In this paper, four sets of pvib, ηi, ζi values and two sets of normal stress test data for the model experiment are given. The normal pressure calculated by the author’s formula using the corresponding ηi and ζi values is similar to the test data. The theory, methods and results provided by the author have practicality and relevance for silo engineering design
