摘要：
Based on the theory of breakage mechanics, the structural soil are conceptualized as binary-medium model consisting of bonding brick and frictional band. Shear band is structural soils' breakage, localization band sprout and development is dynamic process that bonding brick is translating into frictional band. Applied the binary medium model, the speciality and law of structural soil localization band sprouting and expanding are analysised with the numerical simulations of compression under plane strain condition, find that the strain localization on a shear band of structural soil at originally is some sets discontinuous little local breakage area step by step developed, connected and formed the shape of whole destruct with the external load increased; the location different of bug in the soil effected the local shear band germination and progress.
