DYNAMIC DESIGN OF EMBANKMENTS TO RESIST EARTHQUAKES /IN GERMAN/

MOST EMBANKMENTS HAVE BEEN CONSTRUCTED IN ACCORDANCE WITH A PSEUDOSTATIC METHOD, USING A HORIZONTAL EARTHQUAKE ACCELERATION. A RECENTLY DEVELOPED THEORETICAL METHOD IS REPORTED WHICH ENABLES EARTHQUAKE SETTLEMENTS AND DEFORMATIONS FOR A DEFINED CASE TO BE PREDETERMINED REALISTICALLY. THE CALCULATION INVOLVES A COMBINATION OF ALL THE VARIABLES WHICH ARE OF INFLUENCE, IN ACCORDANCE WITH AN OPTIMISTIC, PESSIMISTIC (CONSERVATIVE) AND AN EXTRAORDINARILY UNFAVORABLE INTERPRETATION. DESIGN PRINCIPLES WITH CORRESPONDING ASSUMED SLIP CIRCLES ARE EXPLAINED. THE SPECIAL DYNAMIC SOIL PROPERTIES ARE THE CAUSE OF THE BEHAVIOR OF AN EMBANKMENT. FOR EACH SLIP CIRCLE THERE IS A CRITICAL ACCELERATION AT WHICH THE SAFETY COEFFICIENT BECOMES 1.0. THE VIBRATION BEHAVIOR AND THE DISPLACEMENTS OF AN EMBANKMENT ARE SHOWN BY MEANS OF EXAMPLES. THE NEW METHOD CAN BE USED TO ESTIMATE THE ORDER OF MAGNITUDE OF THE EXPECTED DISPLACEMENTS. THE INCREASED EXPENSE OF DYNAMIC DESIGN IS JUSTIFIED IN PRACTICE. /AUTHOR/
