| Abstract: | The No. 2 pile of Erqi Yangzi River Bridge of Wuhan is tested by self-balanced load method. The stress of the pile and the displacements of the O-cell obtained from self-balanced load test are con- verted to those from the conventional static load test and the ultimate carrying capacity of the pile is determined by the improvable load delivery function method. |
