PILE SUPPORTED STRUCTURE IN LAKE DEPOSITS

ENGINEERING EXPERIENCE DERIVED FROM THE FOUNDATION INVESTIGATIONS, DESIGN, AND CONSTRUCTION OF TWO PILE- SUPPORTED PUMPING PLANTS ON SOFT, LEAN-CLAY LAKE SEDIMENTS IS REPORTED. A COMPLETE DISCUSSION OF TREATMENT OF THE FOUNDATION PROBLEMS IS PRESENTED, WITH DETAILS OF SEVERAL NOVEL TEST METHODS AND FULL-SCALE FIELD OBSERVATIONS. PROJECT REQUIREMENTS ARE OUTLINED WHICH NECESSITATED SITING THE PLANTS IN THE POOR FOUNDATION AREA. WITH GENERAL SOIL CHARACTERISTICS KNOWN FROM WILLARD DAM INVESTIGATIONS, THE EXPLORATION PROGRAM WAS DESIGNED TO LOCATE SPECIFIC SITES WHERE SOILS OF THE GREATEST FIRMNESS EXISTED. FIELD INVESTIGATIONS INCLUDED UNDISTURBED SAMPLING, IN-PLACE PENETRATION TESTS, PILE LOADING TESTS, AND VANE SHEAR TESTS ADJACENT TO THE TEST PILES. SPECIAL LABORATORY TESTS WERE CONDUCTED TO EVALUATE CHANGES IN SOIL COMPRESSIBILITY DUE TO PILE DRIVING AND TO STUDY CHANGES IN PILE BEARING STRENGTH WITH TIME. PROCEDURES FOR THE FIELD PILE TESTING PROGRAM ARE OUTLINED, AND SETTLEMENTS RECORDED DURING AND AFTER FOUNDATION CONSTRUCTION ARE DISCUSSED. VALIDITY AND VALUE OF THE FOUNDATION TESTING PROGRAM WERE CONFIRMED BY THE RESULTS OF SETTLEMENT OBSERVATIONS. /AUTHOR/
