NOTA SOBRE A INFLUENCIA NAS CONSTRUCOES DAS VIBRACOES DOS TERRENOS PROVOCADAS POR EXPLOSOES

THE SAFETY CRITERIA IN THE USA, CANADA AND SWEDEN ARE INDICATED; IT IS CONCLUDED THAT THE CRITERION BASED ON THE VELOCITY OF PROPAGATION OF PARTICLES IS A MEASUREMENT OF THE STRAINS IN A STRUCTURE FOUNDED ON SOIL WHERE THE VIBRATION WAVE PROGRESSES. THE USUAL LIMIT VELOCITY OF THE PARTICLES IN THE SOIL IS 50 MM/S (2 IN/SEC), BELOW WHICH NO DAMAGES ARE TO BE ANTICIPATED IN THE STRUCTURES. THE PROPAGATION CHARACTERISTICS OF BLAST VIBRATIONS SHOULD BE STUDIED IN EACH PARTICULAR CASE. FINALLY IN ORDER TO FACILITATE THE APPLICATION OF SAFE METHODS, SOME DATA ARE PRESENTED BY MEANS OF WHICH THE AMOUNT OF EXPLOSIVE TO BE USED CAN BE CALCULATED IN A FIRST APPROXIMATION. /AUTHOR/
