A DEEP EXCAVATION AND A RAFT FOUNDATION IN SOFT CLAY

THIS IS A CASE HISTORY DESCRIBING A DEEP BRACED EXCAVA- TION IN WHICH FULLY COMPENSATED RAFT FOUNDATION WAS CON- STRUCTED. THE FOUNDATION SOIL IS THE VICTORIA MARINE CLAY, WHICH IS A SOFT NORMALLY CONSOLIDATED DEPOSIT 70-100 FT (21-30 M) THICK AT THIS SITE. OBSERVATIONS WERE MADE ON THE DEFLECTIONS OF THE BRACING AND THE HEAVE OF THE EXCAVATION AND WERE CONSIDERED A NECESSARY PART OF THE DESIGN. OBSERVATIONS HAVE ALSO BEEN KEPT ON THE SETTLEMENT OF THE BUILDING FOUNDATION FOR OVER 1 1/2 YEARS. THE CALCULATED SAFETY FACTORS USED IN BRACING DESIGN AND FOUNDATION DESIGN ARE COMPARED AGAINST THE ACTUAL PERFORMANCE.
