%X Temperature load is the main cause of cracks in mass concrete in construction period. The cracking risk probability and reliability of a roller compacted concrete (RCC) gravity dam are calculated by Monte-Carlo method with factors affecting the cracks in mass concrete as random variables in establishing the limit state function by response surface method based on simulation of temperature control measures. Results demonstrate that the recommended temperature control measures are reasonable. Calculation results of cracking risk probability and reliability reflect that the cracking risks of feature points inside the RCC dam are higher than those exterior to the dam, and the maximum cracking risk appears in the end of the first-phase cooling stage.
