APPLICATIONS

MULTIPLE LARGE-DIAMETER PILES (SPUDS) CAN BE EFFECTIVE AS PART OF A FOUNDATION SYSTEM FOR GRAVITY STRUCTURES IN THE ARCTIC. THE MAIN PURPOSE OF THE SPUDS IS TO HELP TRANSFER HIGH LATERAL ICE LOADS TO MORE COMPETENT SUBSURFACE SOILS. THERE ARE CURRENTLY NO DESIGN GUIDELINES FOR SPUDS. TEST RESULTS AND DESIGN CRITERIA FOR LONG PILES ARE NOT APPLICABLE BECAUSE THEY DO NOT INVOLVE SIGNIFICANT LATERAL SOIL DEFORMATION AND RESISTANCE NEAR THE PILE TIP. A WORK PLAN CONSISTING OF LITERATURE SURVEY, ANALYSIS AND EVALUATION OF THE CURRENT STATE-OF-KNOWLEDGE OF SPUD BEHAVIOR IS PROPOSED. THE COST AND DURATION OF THIS STUDY HAVE BEEN ESTIMATED TO BE ABOUT $35,000 AND FIVE MONTHS, RESPECTIVELY. A FINAL REPORT WILL BE SUBMITTED AT THE END OF THE STUDY.
