Abstract
In this research, the concrete gravity dam by the block layer construction method that uses Portland blast-furnace slag cement is targeted. The autogenous shrinkage that has never been considered in the thermal stress analysis of the concrete gravity dam was examined. Moreover, an appropriate setting method of the analytical modeling and the air temperature in the block layer construction method was examined. As a result, the following was clarified. The autogenous shrinkage exerts a big influence on the thermal stress analysis of the concrete gravity dam. Even when the concrete gravity dam is placed by the block layer construction method, an enough analytical result is obtained by 2-dimensional plane strain analysis. The thermal stress that takes the change of the air temperature into consideration can be analyzed by using the proposed air temperature estimating model.
