A brief introduction is given to the properties of model RAP-1 dynamic pile testing apparatus and more detailed descriptions are given to the functions

operation SAMPLE /D sampling soft-ware system and PAP/4A analyzing soft-ware system of RAP-1 as well as to the auto-processing for pile testing data from dynamic parameter method Case method. SAMPLE/D and PAP/4A are complete in function and easy to operate

which can compensate the inadequate waveforms caused by the changes of some conditions in field measuring and reduce the errors in data analyzing. They can not only he used for in-situ real time analyses but also for analyses after testing.
