Full - Scale Accelerated Loading System, one part of "the Eleventh - Five - Year National Grand Technology Infrastructure Program" is a facility to evaluate the performance and service life of different kinds of pavements subjected to traffic loading under full - controlled environment. While simulating the environments of frigid zone and permafrost zone, the accurate control of air temperature, road temperature and roadbed temperature are the key points and also aporias for the designment. In this paper, numerical simulations are used to determine the design parameters of the frozen soil simulation system. At first, a brief introduction of the Full - Scale Accelerate Loading System was given. Then, the temperature control method of frozen soil simulation system was proposed. Finally, by using finite element simulations, the optimal design of frozen soil simulation system was obtained. This proposed design, which was obtained by finite element simulations, provided significant referents to the ultimate design of the environment simulation system. : {"references": ["Zejiao Dong, Yiqiu Tan, Fengchen Chen, \"Preliminary Design of Testing\nSegment for Accelerated Loading Facility Based on Finite Element\nSimulation Analysis,\" Asphalt Material Characterization, Accelerated\nTesting, and Highway Management: Selected Papers From the 2009\nGeoHunan International Conference (GSP 190), Aug. 2009, pp. 72-78.", "Haleh Azari, Alaeddin Mohseni, Nelson Gibson, \"Verification of Rutting\nPredictions from Mechanistic-Empirical Pavement Design Guide by Use\nof Accelerated Loading Facility Data,\" Journal of the Transportation\nResearch Board, Volume 2057 / 2008, pp. 157-167, Nov, 2008.", "Yuchi Bin, Lu Shixun, Zhou Zuyi, etc., Practical Handbook of\nRefrigeration and Air Conditioning.
