Study on the correlation of macro-fine parameters of surrounding rock in sand and cobble tunnel based on discrete element

As a mixture of soil and rock, the deformation of surrounding rock caused by tunnel excavation in the sandy cobble stratum is affected by the meso-structure of the stratum. In this paper, the mechanical and engineering characteristics of sandy cobble soil are studied in depth using a laboratory larg...
