嵩上げコンクリート重力ダムの設計と解析

It becomes a very usefulmethod to raise the height of the old dam for the functional improvement of a storing reservoir on the ground of the lack of dam site suitable for construction of a new dam and the possibility of construction of raising dam while storing water.
In the present paper, the computationalmethod of a section of raising concrete gravity dam is rearranged. One concrete gravity dam is chosen as an example, and the safety of the raising dam is examined considering the order of raising by means of finite element analysis. Furthermore, the effect of the change of Young's moduli of foundation rock and concrete in the old dam and the raising part, and of water level on the dam is investigated.
