CYLINDER PILE DESIGN ON THE BASIS OF NEW SOIL TEST PROCEDURES

A PROCEDURE WITH A NOMOGRAPH FOR THE DESIGN OF CYLINDER PILES AS RETAINING STRUCTURES IS PROPOSED. A METHOD OF ANALYSIS IS PROPOSED WHEREBY THE EFFECT OF LATERAL STRESS RELAXATION DUE TO A CUT MADE ALONG THE HILLSIDE ON THE STRENGTH AND STABILITY OF THE SOIL AS A FUNCTION OF THE OVERCONSOLIDATION RATIO CAN BE DETERMINED. IT IS SHOWN THAT OVER-CONSOLIDATED SEATTLE CLAYS LOSE APPROXIMATELY 23 PERCENT OF THEIR SHORT- TERM STRENGTH DUE TO LATERAL STRESS RELIEF. FURTHERMORE, THESE SOILS ALSO LOSE 50 PERCENT OF THEIR STRENGTH DUE TO CREEP. THEREFORE, THE SOIL DESIGN STRENGTH TO BE USED IN CALCULATING THE STABILITY OF CUT AND UNRETAINED SLOPES IN THE SEATTLE AREA SHOULD BE IN THE NEIGHBORHOOD OF 27 PERCENT OF THE INITIAL SHORT-TERM STRENGTH OF THE SOILS. /FHWA/
