DYNAMIC STABILITY OF SLOPES

THE PROBLEM OF THE STABILITY OF SLOPES WHICH ARE INFLUENCED BY SEISMIC WAVES IS STUDIED. A HIGH SLOPE CONSISTS OF SOFT SOIL AND IS SUPPORTED ON HARD ROCK. THE SO-CALLED METHOD OF FINITE ELEMENTS IS USED FOR THE ANALYSIS OF THE MOMENTS OF INERTIA. THE ELASTIC SEISMIC WAVES OF THE ROCK FOUNDATION ARE TRANSFORMED BY THE SPREADING IN THE SOFT SOIL IN PLASTIC WAVES. THE LENGTH OF THESE WAVES IS COMPARABLE WITH THE DIMENSIONS OF THE HEIGHT OF THE SLOPE SO THAT ONE MUST RECKON WITH THE ACCELERATION OF THE SLOPE FOR CONTINUOUS WAVES. THE STABILITY OF SLOPES IS CALCULATED BY TWO METHODS: FIRSTLY THE CYLINDRICAL SLIP SURFACES UNDER THE STRESS OF THE ACCELERATIONS WHICH OCCUR THROUGH THE SEISMIC WAVES IS DETERMINED. THE SECOND METHOD IS BASED ON THE MATHEMATICAL THEORY FOR UNSTABLE VIBRATIONS. THE STABILITY OF THE SLOPE IS CALCULATED FOR VARIOUS PHYSICAL PARAMETERS OF THE SLOPE AND VELOCITIES OF SEISMIC WAVES. THE COVERING ABSTRACT FOR THE CONFERENCE IS IRRD NO 306088.
