Abstract: In this paper the working condition of the pre-stressed pier of first river sand sluice and second river discharging sluice and third river sand sluice of Gezhouba project is analyzed. The pre-stressing loss, edge and shrinkage section stress distribution of the piers are also studied and compared with the results of design and test. From above study we recognize that the design of pre-stressed piers is reasonable and working condition is normal.?
