| Abstract: | Through introducing the calculation of reinforcement cage dipole transient induced electromotive force with numerical simulation method, the spatial distribution characteristics has been analyzed and studied, the method to determine the length of the reinforcement cage by two peaks distance has been summed up. The meth- od is reliable and accurate through contrast experiment test being executed with the magnetic logging law to the model piles and engineering piles. Simultaneously it has been discovered that this method is more direct -vie- wing, easier to distinguish and and easv to promote, it has aui proved to be a kind of innovation. Because this method is economically feasible te remarkable social and acanomic hanafits |
