A NEW SYSTEM FOR DYNAMIC PILE TESTING
The use of dynamic pile testing for the determination of axial pile capacity is generally accepted and extensively used,world-wide.The existing equipment is complex and its use requires extensive and repeated training.A new dynamic pile testing system has been developed that reduces the cost of testing and increases testing capabilities by automation of the signal matching analysis so that a capacity prediction is obtained,in the field,in real time,for every hammer blow.The analysis offers the following capabilities in addition to the usual capacity determination by signal matching:(1) the equipment is simple to operate and its use can be learned from the documentation or with only very brief training,(2) a signal matching analysis that is fully automated has been developed for the determination of pile capacity,(3) the maximum compression and tension stresses and their locations along the pile are determined,(4) a warning,is given if the maximum pile compression strengths are nearly reached,a useful tool when driving to rock,(5) a similar capability is available to determine the limits on tension stresses in concrete piles,and (6) selected results are presented in tabular form,that can be supplied to the Engineer at the end of driving if he is not on-site.
