| Abstract: | Based on the method of reverberation matrix,the velocity wave of two-defective pile head under semi-sine impulse exciting is discussed in the paper.The defects of pile are simplified by changing the cross-section areas of defective elements.The velocity wave of defective pile head and intact pile head are compared.The velocity wave of defective pile head is analyzed,which is effected by defect extent.Many significant conclusions are obtained. |
| Keywords: | method of reverberation matrix pile defect velocity wave |
