The ballast model is established in PFC, which is made of rigid sub-blocks bonded together. Based on the macroscopic morphology and angular characteristics of ballast, a method is proposed to quantify the accuracy of the ballast model. The influence of the modeling parameters on the accuracy of the ballast model is analyzed, and the range of the accuracy is delineated to determine the modeling parameters of the fine ballast model. Uniaxial compression DEM simulation of the proposed fine ballast model to verify its feasibility for simulating ballast crushing. The results show that the proposed fine bonded ballast model can better reproduce the complex morphology of ballast and reflect the angular and concave features of the real ballast, and it can basically reach 95% accuracy. Taking the force-displacement curves of ballast uniaxial compression experiments and ballast crushing forms as the evaluation basis, the proposed fine bonded ballast model can better simulate the crushing response of the real ballast, and compared with the ball clusters ballast model, the bonded ballast model more accurately reflects the crushing situation of the real ballast.
