Abstract: The soil material consists of numerous individual particles, and the shape of these particles directly impacts the macro-and micro-mechanical properties of the soil. Through microscopic observation and considering particle shape effects, a series of discrete element simulations were conducted on tailings particles. Using CT scanning and image processing techniques, the liquefaction characteristics of real particle samples and circular particle samples under three different confining pressures we... More
