| Abstract: | The joint forming technique of the Shapai RCC arch dam is stressed on the combination of induced joint with transverse joint. On the basis of the experience of the joint forming technique at home and abroad, the joint structure and joint grouting system have been deepened. A new technique of pre cast gravity type concrete formwork for joint forming and joint re grouting was put forward and was successfully applied to the construction. Meanwhile the initiation and breakthrough of the jointing of RCC arch dam also have been gained, which provides the important experience for the design of high RCC arch dam with the height of over 100 m. |
