摘　　要：The dynamic strain field under the action of blasting load is measured by means of a super-dynamic strain system and a CS2092H dynamic measuring analysis system, and the relation between the peak valwe of strain and the quantity of explosive charge is obtained. And the authors probe into the mechanism of soot descaling of soot-delivery pipe under the action of blasting, and offer an effective method to clean soot in soot-delivery pipe. The study provides a theoretical basis for a further study on blasting descaling or soot-delivery pipe.The dynamic strain field under the action of blasting load is measured by means of a super-dynamic strain system and a CS2092H dynamic measuring analysis system, and the relation between the peak valwe of strain and the quantity of explosive charge is obtained.
