PERFORMANCE ANALYSIS OF CYLINDER-BEAM RETAINING WALLS- SEATTLE FREEWAY-SENECA STREET TO OLIVE WAY

RETAINING WALLS FOR PORTIONS OF THE SEATTLE FREEWAY WERE MADE FROM VERTICAL CYLINDRICAL BEAMS CAST IN AUGERED HOLES PRIOR TO EXCAVATION. PRESENTED ARE ILLUSTRATIVE RESULTS OF ANALYSIS OF INCLINOMETER DATA FROM INSTALLATIONS IN SOME OF THESE CYLINDERS, SEEKING TO DETERMINE CHARACTERISTICS OF THE LATERAL PRESSURES INTERACTING BETWEEN THE EARTH AND CYLINDERS. GENERAL FEATURES OF THE LOAD DISTRIBUTION PATTERN ARE POSTULATED BY SELECTING VARIABLES IN A POLYNOMIAL SINGULARITY FUNCTION, AND THE COEFFICIENTS ARE FOUND BY REGRESSION METHODS, SUBJECT TO BOUNDARY CONDITIONS IMPOSED ON THE BENDING MOMENT AND ITS DERIVATIVES. IT IS PROPOSED THAT FINITE-ELEMENT ANALYSES WILL BE USED TO AID IN DEVELOPING POSTULATED LOAD DISTRIBUTION PATTERNS AND THE RESULTS OF ONE SUCH "PILOT" ANALYSIS IS INCLUDED IN THIS REPORT. THESE ANALYSES WILL BE EXTENDED TO TAKE INTO ACCOUNT THE VARIATIONS IN SOIL PROPERTIES AND THE CROSS-SECTION CONFIGURATION. WORK THUS FAR ACCOMPLISHED LEADS TO A PARTIAL DESCRIPTION OF THE PERFORMANCE OF THE CYLINDERS. THIS INTERIM REPORT DEMONSTRATES THE VALIDITY (AND LIMITATIONS) OF THE ANALYTICAL TECHNIQUES THAT HAVE BEEN DEVELOPED. /FHWA/
