Abstract
In a Compressor foundation undergoing excessive vibrations, its amplitudes at operating frequency and natural frequency in free vibrations were monitored. Also in-situ dynamic properties were determined to check design and predict its response. Since the soil constants are strain depondent, two sets of computations were done (1) from the known soil constants and permissible amplitudes and (2) from the known soil constants and the observed amplitudes. The soil constants were corrected for confining pressure and relative density of the non-cohesive soil also. Both weightless spring theory (Barkans’ Method) and elastic half space theory were used in predicting the response. A critical evaluation of these two design approaches has been made and necessity to monitor the performance of machine foundations is highlighted.

Behavior of Compressor Foundation – Predictions and Observations
In a Compressor foundation undergoing excessive vibrations, its amplitudes at operating frequency and natural frequency in free vibrations were monitored. Also in-situ dynamic properties were determined to check design and predict its response. Since the soil constants are strain depondent, two sets of computations were done (1) from the known soil constants and permissible amplitudes and (2) from the known soil constants and the observed amplitudes. The soil constants were corrected for confining pressure and relative density of the non-cohesive soil also. Both weightless spring theory (Barkans’ Method) and elastic half space theory were used in predicting the response. A critical evaluation of these two design approaches has been made and necessity to monitor the performance of machine foundations is highlighted.
