BEHAVIOR CHARACTERISTICS OF CFRD IN CONSTRUCTION PERIOD
In this study, we analyzed the settlement deformation behavior from the change of the load on the dam structure through the CFRD construction behavior analysis according to the measurement data of Daegok dam, and performed a comparative analysis with foreign CFRD measurement. From measuring settlements of Daegok dam with depth, overall behavior was evaluated to be stable, showing consistent settlement with measured data of other CFRD dams. In addition, construction modulus, void ratio and shape factor was also identified to be major factor in predicting the settlement behavior during construction of CFRD-typed dam from analysis of data measured from 38 CFRD-typed dam. According to the analysis of 38 CFRD measurement, the maximum internal settlement is proportional to the void ratio. In the relationship between the maximum internal settlement and the height of a dam, there are 26 dams that have its relative modulus in between 0.001 and 0.01. The average of general CFRD, the relative modulus of maximum internal settlement and the height of a dam is estimate to be 0.005. In case of a low void ratio, the construction modulus was high with its shape factor below 4. On the other hand, in case of a high void ratio, the relative settlement ratio was high with its shape factor more than 4.
