Title:     
 
Einfluss des Sohldrucks auf die vertikalen Schwingungen von Blockfundamenten
 
Abstract:     
 
Auf einem Lehmvorkommen wurde ein Blockfundament gegründet und der Frequenzgang der Schwinggeschwindigkeit bei vertikaler Anregung gemessen. Danach wurde die Masse des Fundaments auf gleicher Grundfläche verdoppelt und die Messung wiederholt. Die Auswertung der Ergebnisse nach dem Analogieverfahren [1] zeigt den Einfluss des Sohldrucks auf die Feder- und Dämpfungswirkung des Baugrundes infolge seiner nichtlinearen Spannungs-Dehnungslinie.

Effect of the base pressure on vertical vibrations in block foundations.
The vibration velocity (for vertical excitation) was measured in a foundation block constructed on clay. The mass of the foundation was then doubled (with identical surface area) and the measurement was repeated. The analysis of the results based on the analogy technique [1] illustrates the influence of the base pressure on the spring and attenuation effect of the soil due to its non-linear stress-strain characteristics.
