Abstract: Based on the analyses and application of the rapid concrete construction technologies for the second
stage, the third stage dam of Three Gorges project adopted a lift thickness 3m for the foundation non
restriction
zone, dam pensation for the joint of the partment of the concrete with short age, and
the longitudinal joint
free concrete placing for the No. 2 right non
overflow dam field. The third stage dam was
completed half a year ahead the schedule and no concrete crack appeared. The application proved that these new
technologies of rapid construction are feasible and are valuable to the other projects.
Key words: construction of hydraulic engineering; rapid construction; new technology; concrete dam; Thr
