Thermal-Structural Modelling and Temperature Control of Roller-Compacted Concrete Gravity Dam: A Parametric Study

This research is a Parametric study that investigates the temperature and thermal stress distributions in Roller Compacted Concrete (RCC) dams. The analysis used in this study involved the RCC placement temperature, the Modulus of Elasticity, tensile strain capacity, the placement schedule of RCC layers, the number of layers, and the thickness of each layer. The Metolong Dam Project in the South African state of Lesotho is used in this research as a case study, in addition to ANSYS, a well-known computer code. The sensitivity of each of the parameters listed above is investigated, and the results are presented in tables and graphs. Conclusions are drawn to better understand the effect of each parameter on the temperature distribution and thermal stress in the RCC dams.
