DEEP FOUNDATION PILES. EXAMPLE OF A SPECIAL WORKING TECHNOLOGY

CONSTRUCTION OF THE SECOND SECTION OF THE ROMAN UNDERGROUND RAILWAY SYSTEM RECENTLY POSED THE DIFFICULT PROBLEM OF CROSSING THE TIBER. THE PROBLEM WAS SOLVED BY THE CONSTRUCTION OF A THREE SPAN BRIDGE. THE STRUCTURE CONSISTS OF TWO LATERAL PRESTRESSED SLABS FOR THE PEDESTRIAN AREA AND ROADWAY. A THIRD REINFORCED CONCRETE SLAB POSITIONED IN THE MIDDLE AND CONNECTING THE PREVIOUS TWO, ACTS AS THE RAILWAY BRIDGE. THE BRIDGE FOUNDATION IS CONSTRUCTED ON LARGE BORED PILES WITH A DIAMETER OF 1.50 M AND A MAXIMUM LENGTH OF APPROXIMATELY 70 CM. THE PILES ARE BORED TO A DEPTH OF 64 M, BENTONITE SUSPENSION BEING USED SIMULTANEOUSLY FOR THE PURPOSE OF GUARANTEEING THE STABILITY OF THE CAVITY AND REDUCING FRICTION BETWEEN THE SOIL AND THE STEEL CASING. THE PAPER DESCRIBES PLANNING CRITERIA AND TECHNOLOGY RELEVANT TO PILE CONSTRUCTION. THE PILE FOUNDATIONS WERE CONSTRUCTED BETWEEN MARCH AND JULY 1971. FOUNDATION COSTS REPRESENT APPROXIMATELY ONE-FIFTH OF THE TOTAL CONSTRUCTION EXPENDITURE. THE COVERING ABSTRACT FOR THE CONFERENCE IS IRRD NO 306088.
