MEASUREMENTS OF VIBRATIONS CAUSED BY CONSTRUCTION EQUIPMENT AND BLASTING

THE INVESTIGATION OF VIBRATIONS RESULTING FROM CONSTRUCTION ACTIVITY EMBODIED THREE PRINCIPAL OBJECTIVES: (1) TO FORMULATE A METHOD OF HOUSE INSPECTION WHICH WOULD ENABLE THE EVALUATION OF PROPERTY DAMAGE CLAIMS ARISING FROM CONSTRUCTION WORK; (2) TO MEASURE THE VIBRATION LEVELS PRODUCED BY DIFFERENT TYPES OF CONSTRUCTION EQUIPMENT; AND (3) TO SET-UP AND MAINTAIN A VIBRATION LEVEL MONITORING SERVICE ON EXPLOSIVE CHARGES USED IN THE EXCAVATION OF A SEWER TUNNEL, AND TO ENSURE THAT RECOMMENDED CHARGE LEVELS WERE NOT EXCEEDED. EARLIER STUDIES ARE DISCUSSED INCLUDING INVESTIGATIONS BY THE U. S. BUREAU OF MINES, CRANDELL'S STUDIES INVOLVING GROUND VIBRATION INTENSITY AS A MEASURE OF THE DAMAGE LIKELY TO BE CAUSED, AND EDWARDS AND NORTHWOODS STUDY OF VELOCITY CRITERIA. THE EQUIPMENT DESIGNED AND USED DURING THE COURSE OF THE REPORTED INVESTIGATION IS DISCUSSED IN DETAIL AND THE RESULTS OF THE LATTER TWO PHASES OF THE PROJECT ARE FULLY DOCUMENTED. THESE INCLUDE RESULTS OF THE TESTS TO DETERMINE THE VIBRATION LEVELS FROM CONSTRUCTION EQUIPMENT, TESTS TO MONITOR THE VIBRATION EFFECTS OF BLASTING AND MEASUREMENTS OF VIBRATION CARRIED OUT DURING THE DEMOLITION OF A BRIDGE BY MEANS OF THE WRECKING BALL. IT IS CONCLUDED THAT THE REPORTED DATA CAN SERVE AS THE MEANS TO PREDICT VIBRATION LEVELS RESULTING FROM A FAIRLY WIDE RANGE OF CIRCUMSTANCES AND OUTLINES A PROCEDURE WHEREBY THIS CAN BE ACHIEVED. IN THE BLASTING MEASUREMENTS MADE IT WAS ESTABLISHED THAT THE VIBRATION LEVELS PRODUCED BY BLASTING AGREED REASONABLY WELL WITH THOSE PREDICTED. A NEW DESIGN OF SEISMOGRAPH IS ILLUSTRATED AND RECOMMENDATIONS FOR FUTURE RESEARCH WORK IN THE FIELD OF VIBRATION MEASUREMENT. /RATAOC/
