CORRELATION OF SEISMIC VELOCITIES WITH EARTHWORK FACTORS (INTERIM REPORT)

THIS RESEARCH PROJECT IS INTENDED TO DETERMINE IF SEISMIC VELOCITIES CAN BE USED TO IMPROVE THE ACCURACY OF DESIGN EARTHWORK FACTORS. THE PROCEDURES USED BY THE CONTRACTOR FOR EARTHWORK CONSTRUCTION WERE INVESTIGATED. DENSITIES WERE TAKEN IN THE CUT AREAS AT FINISHED GRADE. THESE VALUES WERE COMPARED TO THE AVERAGE COMPACTED IN-PLACE DENSITIES OF THE FILLS AND THE DIFFERENCE IN VOLUME WAS CALCULATED. FINAL CUT AND FILL SLOPE ANGLES WERE MEASURED AND COMPARED TO THE DESIGNED SLOPE ANGLES AND THE DIFFERENCE IN VOLUME WAS CALCULATED. THE TOTAL VOLUME OF BOULDERS PROTRUDING FROM THE CUT FACES WAS ESTIMATED. THE TOTAL VOLUME OF BOULDERS THAT ROLLED DOWN SLOPES AND OUT OF THE EMBANKMENT AREAS WAS ESTIMTED. A TOTAL OF FORTY-TWO SEISMIC REFRACTION LINES WERE OBTAINED FROM THE ENTIRE LENGTH OF THE PROJECT. FIELD EARTHWORK FACTORS, DETERMINED AFTER CONSTRUCTION, WERE COMPARED TO DESIGN EARTHWORK FACTORS AND TO THE SEISMIC VELOCITITES OBTAINED IN THE CUT AREAS. A TABLE WAS DEVELOPED COMPARING SEISMIC VELOCITIES TO EARTHWORK FACTORS. /AUTHOR/
