Abstract

Through the low strain dynamic test in engineerings, we found that the wave velocity is raised with time. Reasons for the phenomenon are analysed with the theory of stress wave propagation. We found that the increasing of the velocity of the test pile is mainly effected by the of lateral soil, because a soil layer close to the surface of the pile will gradually be formed in a period after piles sunk. When the pile shifted, the soil layer will move together, just like enlarging the section size of the pile. This increases the bearing capacity of the pile. So it can be considered that the enlarging of the velocity is consistent with the increasing of the pile bearing capacity. The study of the velocity increace is benificial for the investigation of the time effect of the static pressure pile bearing capacity.
