Preliminary Design of Frozen Soil Simulation System Based on Finite Element Simulation
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.
