Abstract
Hydraulic mass concrete is prone to developing temperature cracks due to the accumulation of hydration heat. Numerical simulation of temperature control is a key technology for crack prevention. This paper focuses on numerical simulation methods and parameter calibration, systematically reviews the modeling theory in this field, analyzes the research progress of core elements such as hydration heat models and environmental boundary conditions, expounds the current research status in terms of research object expansion, numerical method verification, and scheme parameterization optimization, and dissects existing issues such as insufficient parameter transferability, multi-objective optimization conflicts, and difficulties in implementing multi-field coupling. Finally, it summarises the technical consensus formed and proposes future research directions in cross-engineering parameter calibration, multi-measure collaborative optimisation, and digital closed-loop control.
