Quantitative Research Of Reflected Wave Uesd In Testing Integrity Of Pile

Low-strain reflected wave by transient hammering is widely used in testing integrity of pile for its convenience,reliability and economic advantages.The reflected wave method is continuous developed and improved in practical application.People also want to know the accurate degree of the defects in the pile in order to take appropriate remedial measures for the sake of security and economy.Testing quantitative research in testing integrity of pile become the focus.Impact of several parameters affecting the pile cap speed time-domain waveform curve is get by the simulation of Low-strain reflected wave by transient hammering by Matlab.Finally,the theory was verified by the cases curves in condition of pile surround by soil or none.
