The database management of piling induced ground vibrations

Abstract

The storing of ground vibration signals produced by pile driving have been stored in a database on a Nimbus personnel computer. The signals were recorded on a purpose built data logger in the form of time history traces, analysed to calculate the maximum values and then these values transferred. This report covers the design of the transfer systems and the database itself, the manner in which the transfers were effected and a description of the support software produced. Data acquisition is also covered to provide an insight into why certain database design features were included. An expert shell system has also been designed, allowing predictive estimations of ground vibration levels to be achieved. Comparisons between the two systems suggest a good level of compatibility.
