However, parameters such as elastic modulus and poisson ratio of the glass spherical particles and the metal spherical particles are greatly different from those of natural coarse particles, and the strength cannot be changed according to research requirements, so that the relevant characteristics of the coarse particle soil in the field state cannot be reflected more truly. The cement ball particle can realize the same stress condition as the natural coarse particle material and can also achieve the purpose of controlling the particle breakage rate in the test by adjusting the cement ratio and the particle strength of the cement ball, but because the preparation usually adopts manual repeated kneading, a great deal of manpower and time are required, the efficiency is lower, and the particle size after molding is different, so that the requirement of the test is difficult to meet.
