optimization of time and temperature of dam construction for thermal analysis of roller compacted concrete dam

The growing number of roller-compacted concrete dams built worldwide demand suitable methods to reduce the risk of thermal cracks. in roller-compacted concrete dams, large amounts of concrete are usually poured in a short time, and the heat generated by the hydration of the cement leads to an increase in temperature in the body of the dam, which results in a significant heat slope. in this research, the abaqus finite element software was used for thermal analysis of the dam during construction and concreting. the method of applying thermal changes is as follows: hypothetical 50-cm layers are considered for the structure, with each layer taking up 72 hours of analysis time. in general, the problem under analysis is analyzed 12 times. each analysis is based on the start of the project in different months of the year to achieve the optimal construction time based on the maximum temperature in the dam’s concrete and the stresses created by it by collecting the information and using the perceptron network algorithm. the perceptron algorithm and machine learning were performed on the 12 mentioned analyses, and then the process output was generated for 365 days of the year as the start of the project. finally, the optimal time to start construction was obtained.
