SEISMIC SURVEYS FOR HIGHWAY INVESTIGATIONS IN MASSACHUSETTS

AS A RESULT OF 269 GEOLOGIC-SEISMIC STUDIES MADE ALONG PROPOSED HIGHWAY LOCATIONS, ANALYSIS OF COMPARISONS OF 90 REPORTS HAS RESULTED IN CHANGES IN FIELD PROCEDURE, MODIFICATIONS OF INSTRUMENTS, STUDY OF EMPIRICAL VERSUS ANALYTICAL METHODS OF COMPUTING THICKNESS OF SOIL UNITS, AND INCEPTION OF FIELD MODEL ELASTIC-PROPERTY MEASUREMENT SUPPORTED BY LABORATORY VELOCITY AND ELASTIC PROPERTY MEASUREMENT OF ORIENTED FIELD SAMPLES. EQUIPMENT AND FIELD PROCEDURE, INTERPRETATION OF TRAVELTIME CURVES, AND COMPARISONS OF PREDICTED AND ACTUAL CONDITIONS ARE DISCUSSED. FOUR CASE HISTORIES ILLUSTRATE SOME PROBLEMS ENCOUNTERED OCCASIONALLY IN SHALLOW BOUNDARY SEISMIC INVESTIGATIONS AND REVEAL THE DANGER OF RELYING ON SPEED ALONE FOR IDENTIFICATION OF A CONCEALED SEISMIC LAYER. /GA/
