Comparison of Methods for the Measurement of the Angle of Repose of Granular Materials



The angle of repose—the maximum angle that allows a heap of soil to remain stable without failing—is an important property of soils and affects the safety and costs of projects such as slopes or retaining walls. But several methods have been proposed to measure it, which might produce confusion in practice and research. The angles of repose obtained using six different methods for six different sands are compared here in order to quantify and explain the differences and determine some of the factors that influence the angle’s value. The results show that the highest values are obtained with the ASTM International and Cornforth methods, followed by scoop deposition (6 % smaller), the Santamarina and Cho dry method (12 % smaller), and the cone lifting method (35 % smaller). Both the cone lifting method and the Santamarina and Cho wet method produce segregation of the finer particles for sands having a specific gravity greater than 2.7 and a difference of extreme void ratios larger than 0.3.
