Basic theory of high strain dynamic testing method for one-dimensional wave theory, hammer for pile under the action of stress wave spread along the pile with the velocity c, caused the pile cross section produce movement.
High should be the basic theory of dynamic measurement method is one-dimensional wave theory, pile hammer action under the stress wave velocity C to propagate along the pile, causing the pile cross section in motion.
High strain dynamic measurement is the basic theory of one dimensional wave theory, pile foundation under the effect of hammering, stress wave to wave velocity C along the pile spread, caused by movement of the pile section.
