Study on the Transmit Rules of Stress Wave for Low Strain Test Pile

The transmit course of stress wave for low strain test pile is a complicated problem.The transmit rules of resistance wave of soil around pile and upward traveling wave and downward traveling wave of pile for low strain test pile are studied,Theoretically with the calculation program programmed according to the theory stated in literatures,and the impaction of different soil around and below the pile for transmit process of upward and downward traveling wave in pile are stated.The mesh of traveling wave and the transmit rules picture reflect directly the process of wave transmitting in piles.
