【Abstract】 The principle of reflect wave method inspects pile integrality and frequency-initial velocity method conferms single pile capacity is introduced. This method has fast and lossless advantages and so on. It can not only inspect pile disfigurement, but also conferm single pile capacity through frequency-initial velocity method. The result approaches static load experimentation, and it can satisfy the requirement.更多还原
