A foundation pile analyzer based on instant mechanical impedance theory is developed on LabVIEW in the case of investigating the existing foundation pile testing theories and their corresponding testing methods

which is used to acquire

analyze and store the impulse exciting signal obtained by force sensor and the response signal obtained by the piezoelectric accelerometer on the spot.As is shown from the testing result of comparison between the B&K2034 and foundation pile analyzer

the foundation pile analyzer not only comes up to the applying requirement of the testing engineer but also shortens the testing and analying time.The analyzer with friendly panel

simple operation procedure and powerful analyzing function can be popularized in our country after further be improved.
