Study of Temperature Curling Stresses on Visco-Elastic Character Cement Concrete Double-lay Pavement

摘要

The formulas for calculating temperature curling stresses of double-layer (direct, bonded and separate) airport pavement were derived by using finite elements method, visco-elastic theory and Goodman model theory, from which the relevant computer program VT23 was developed by way of initial strain incremental finite elements method. Finally, the temperature curling stresses of double-layer (direct) airport pavement were figured out by employing computer programs VT23, which were confirmed by insitu measurements of an existing airport, with which the effective method on correct calculation of temperature curling stresses of airport pavement was provided. The method described in this paper are valuable realistically and practically.
