In order to understand the coincidence between the theoretical calculation and the actual situation of the high-piled wharf，the strain monitoring system is installed on the main components to measure the strain values of the wharf components under three working conditions：ship berthing，stacking on wharf surface，and quay crane operation. The monitoring results are analyzed and compared with the theoretical calculation values. The results show that：1）There are differences between the field monitoring results and the theoretical modeling results，but their trend is consistent. 2）The reinforcement scheme is effective. 3）We have a direct understanding of the actual stress condition of wharf components.
