A Cylindrical Erosion Test Apparatus for Erosion Tests on Samples from Yigong Landslide Dam
To quantitatively measure the erodibility of soil including the critical shear stress and the erosion rate, a new measurement system is proposed. The measurement system contains a cylindrical erosion test apparatus (CETA) and a method for calculating shearing stress. The CETA was designed to measure the relationship between the velocity and erosion rate, which was mainly composed of a structure system, a transmission system, an erosion test system, a desilting circulatory system, and a control and data acquisition system. On the basis of the proposed new method, single-size soil samples from the Yigong landslide dam were collected for erosion tests. It is noted that the erosion rate from the apparatus is reliable, which is on the same order as that of the experimental results performed by Briaud. This apparatus can be utilized to analyze the shear stress. The hyperbolic relationship between erosion rate and shear stress is found by proposing the accurate calculation method of shear stress. The hyperbolic model of erosion rate versus shear stress is verified.
