Charge Calculation for Underwater Blast Demolition and Its Application

Abstract

It appears to be an effective method to demolish concrete containers or container-like structures by underwater blast. As compared with conventional blast by charge within drilled holes, underwater blast has advantages in some respects such as simplicity of work process, lower cost, lower noise, less effect of air blast wave, and better control of fragments. In this paper, equations for underwater blast charge calculation are analyzed and derived for cylindrical and rectangular structures on the basis of properties of underwater blast loading, strength and dynamic characteristics of structures, and two examples of application are given.
