| Abstract: | Describes the working principle of hydraulic vibration hammer.The single degree of freedom model of hammer-pile-soil was established.The application of adaptive vibratory pile was brought forward innovatively based on resonance theory,and a method of on-line measuring soil parameters was also put forward.The results show that the model of extended least squares algorithm with a forgetting factor can identify the soil parameters on-line well. |
