Abstract
This study present basic consideration to evaluate the thermal behavior in road tunnel-ground. In this study, the extended Kalman filter which was incorporated with the one-dimensional finite element thermal analysis in order to identify unknown the thermal coefficients in tunnel-ground. And then, the estimated in tunnelground temperatures from identified the thermal coefficients are compared with the observed temperatures of actual tunnel-ground. Finally, numerical examples are worked out to demonstrate the usefulness of this method in identification of the thermal characteristics and evaluation and/or estimation of thermal behavior in road tunnel-ground.
