Influence of Explosive Lining on Soil Physical Performance
The paper introduces the experiment procedures of explosive lining and explosive enlarging cavity in soil, and practical parameter of explosive enlarging cavity are presented. The practical physics parameters of soil based on explosive enlarging cavity and explosive lining are analyzed. The research shows that the enlargement affects the initial density of soil in the surrounding soil of explosive lining and cavity, which forms the higher density. Also there is no low density zone so-called. The initial compactness of the soil that is near cavity and lining is enhanced either by explosive enlarging cavity or by explosive lining. Performance index of soil such as natural density, dry-density, saturation will be reduced along with enlarging distance from soil to center zone of explosion.
