Title:

CYLINDER PILE RETAINING WALL

Accession Number:

Record Type:

Component

Abstract:

THIS PAPER DISCUSSES THE CONDITIONS ENCOUNTERED DURING CONSTRUCTION OF THE SEATTLE FREEWAY, ROUTE OF INTERSTATE 5 THROUGH SEATTLE, WASH., NECESSITATING A CHANGE IN DESIGN OF RETAINING WALLS, FROM THE CONVENTIONAL REINFORCED CONCRETE CANTILEVER OR COUNTERFORT WALL TO UTILIZATION OF CAST-IN- PLACE CONCRETE CYLINDERS WITH WELDED STEEL BEAM REINFORCEMENT. ALSO DISCUSSED ARE THE GEOLOGICAL AND GEOGRAPHICAL PROBLEMS WHICH COMBINED TO CREATE MASSIVE FOUNDATION FAILURES REQUIRING THE CHANGE IN DESIGN CONCEPT, AS WELL AS THEIR SOLUTION AND THE CONSTRUCTION TECHNIQUES INVOLVED. ALTHOUGH EXPENSIVE, THE CYLINDER PILE RETAINING WALL PROVIDES A METHOD OF CONTROLLING EARTH MOVEMENTS BY PLACING THE STRENGTH OF THE WALL INTO THE SOIL BEFORE EXCAVATION BEGINS. ALSO COVERED ARE THE DESIGN OF A 57-IN. DIAMETER CONCRETE CYLINDER, THE ORIGINAL ASSUMPTIONS USED FOR LOAD AND RESISTIVE CAPACITY OF THE CLAY MATERIALS, AND THE REASONS FOR THE VARIOUS ASSUMED VALUES AND THEIR LOCATIONS. ANALYSIS IS ALSO GIVEN FOR THE JACKING LOAD TESTS RUN ON THE CYLINDERS, AS WELL AS A DISCUSSION OF THE DIFFERENCES BETWEEN THE TEST AND CALCULATED VALUES FOR SUCH ITEMS AS THE LOAD-CARRYING CAPACITY OF THE LARGE CYLINDERS, THE LOCATION OF THE NEUTRAL AXIS, THE TENSION CARRYING CAPACITY OF CONCRETE, THE COEFFICIENT OF HORIZONTAL SUBGRADE REACTION, AND THE BEHAVIOR OF PRECONSOLIDATED CLAYS DURING EXCAVATION OPERATIONS. OBSERVATIONS MADE FOR A ONE-YEAR PERIOD ON THE CYLINDER WALL ARE GIVEN, TOGETHER WITH A DISCUSSION OF THE ABILITY OF THE CYLINDER TO FUNCTION AS A RETAINING WALL UNDER WORKING LOADS. /AUTHOR/
