FIED STUDY OF SURCHARGE EFFECTS ON A STEEL SHEET PILE BULKHEAD

THE RESULTS AND ANALYSIS OF A FIELD STUDY CONDUCTED TO DETERMINE SURCHARGE EFFECTS ON A STEEL SHEET PILE BULKHEAD ARE PRESENTED. SLOPE INDICATOR AND STRAIN GAGE DATA WERE USED TO DETERMINE THE LOADS, SHEARS, MOMENTS AND DEFLECTIONS AT ONE INSTRUMENTED PILE LOCATION. THESE RESULTS ARE COMPARED TO THE RESULTS OF THEORETICAL CALCULATIONS. FIELD INFORMATION WAS OBTAINED THROUGH THE USE OF STRAIN GAGES, SLOPE INDICATORS AND TRANSIT AND TAPE SURVEYS. THE THE PERFORMANCE AND ACCURACY OF THE INSTRUMENTATION AND DATA ARE REVIEWED WITH RESPECT TO THE EFFECT ON THE RESULTS. LARGE AXIAL LOADS AND MOMENTS WHICH DEVELOPED ON ONE OF THE INSTRUMENTED SHEET PILING DUE TO DRIVING INTO SOIL WERE OBSERVED. THE DEVELOPMENT OF SOIL ARCHING OR OTHER MEANS OF REDUCING LOAD ON THE BULKHEAD WAS EVIDENT. IT IS CONCLUDED THAT THE EFFECTS OF WALL FRICTION SHOULD BE INCLUDED WHEN FLEXIBLE BULKHEADS WITH GRANULAR SURCHARGES ARE DESIGNED. IN ADDITION, THIS STUDY CORROBORATED THE RESULTS OF PREVIOUS FIELD STUDIES WITH RESPECT TO OBSERVED MOMENT REDUCTION (COMPARED TO THE THEORETICAL) FOR BULKHEADS WHEN NORMALLY LOADED BY BACKFILLING. /AUTHOR/
