In order to explore the temperature rise mechanism of rock-filled concrete,adiabatic temperature rise tests were conducted on rock-filled concrete with six different rockfill ratio,three different initial pouring temperatures,and three different rockfill grades.The effects of rockfill ratio,initial pouring temperatures,and rockfill grades on the adia-batic temperature rise and temperature rise rate curves of rock-filled concrete were analyzed.A universal model of adi-abatic temperature rise rate of rock-filled concrete was proposed based on the adiabatic temperature rise law,which is then used to describe the variation of adiabatic temperature rise rate with age.The adiabatic temperature rise rate mod-el is simple and has a good effect on describing the adiabatic temperature rise and temperature rise rate of rock-filled concrete.The research results have laid the foundation for establishing a concrete adiabatic temperature rise model and are expected to analyze the temperature rise mechanism of rock-filled concrete through dynamic analysis.
