PILED FOUNDATION FOR A RAILWAY EMBANKMENT

PFAHLGRUENDUNG EINES EISENBAHNDAMMS

IT WAS NECESSARY TO CONSTRUCT A NEW RAILWAY EMBANKMENT OF 7 M HEIGHT VERY CLOSE TO AN EXISTING TRACK CARRYING HIGH-SPEED TRAFFIC FOR 18 HOURS DAILY. SINCE THE SUBSOIL WAS EXTREMELY SOFT, WITH LOW UNDRAINED STRENGTH, THE RISK OF FAILURE AND OF LARGE HORIZONTAL DISPLACEMENTS OF THE EXISTING TRACK HAD TO BE TAKEN INTO ACCOUNT. A SUFFICIENTLY SAFE AND ECONOMICAL SOLUTION WAS PROVIDED BY FOUNDING UPON A GRID OF TIMBER PILES PROVIDED WITH SEPARATE PRECAST CONCRETE SCREW POINTS, THE MINIMUM GRID SPACING BEING 1.3 M. THIS TYPE OF CONSTRUCTION WAS EMPLOYED ON 38 PER CENT OF THE TOTAL AREA, WHICH ENSURED A RELIABLE ARCHING ACTION OF THE EARTH FILL. THE AVERAGE LENGTH OF PILE WAS 8 M, THE TOTAL NUMBER OF PILES WAS 1800, THE MAXIMUM SETTLEMENT WAS 13.4 CM AND NO HORIZONTAL DISPLACEMENT OF THE TOE OF THE EMBANKMENT WAS OBSERVED. THE COVERING ABSTRACT FOR THE CONFERENCE IS IRRD NO 306088.
