Abstract

Abstract

In order to obtain the temperature field of surrounding rock and the development law of thawing circle for highway tunnel in permafrost regions, the calculation method of thawing circle for surrounding rock was established, the calculated values and measured values of thawing circle depth and surrounding rock temperature were compared, and the finite element method was adopted to analyze the influence of support on the thawing circle. Analysis result shows that the average error of surrounding rock temperature is no more than 0.6℃, the error of thawing circle depth is no more than 10%, so the calculated value has better accordance with the measured value. When the time of operating shotcrete delays 1 d, the thawing circle depth increases by10 cm. When the thickness of shotcrete increases by 5cm, the thawing circle depth increases by about 10 cm. The thawing circle depth with molding temperature of 15 ℃ for the first molding concrete increases by about 10 cm compared to the molding temperature of 5 ℃. When the thickness of insulation board increases from 5cm to 20 cm, the thawing circle depth decreases by2/3. The insulation board and the hydration heat of secondary molding concrete have big influence on the thawing circle depth. The thawing circle depth with wind speed of 3. 0m·s^-1 in hole decreases by 10-20 cm compared to wind speed of 1.0 m·s^-1 in hole. 30, 60, 90, 120 d after shotcrete being operated, the thawing circle depths at air temperature of 8 ℃ in hole are1. 25, 1. 31, 1. 35, 1. 40 times of thawing circle depths at air temperature of 2 ℃ in hole respectively. Obviously, air temperature in hole should be controlled at 3 ℃-5 ℃, the support should be operated as early as possible after surrounding rock excavation, and low heat or medium heat cement should be used to decrease the hydration heat released by concrete.
