Abstract
This paper summarizes the results of a research project conducted at the U.S. Army cold regions research and engineering laboratory (crrel) permafrost tunnel. The relationships between the ground temperature, the roof span dimensions, and the vertical convergence rate of the crrel tunnel correlate with a combined exponential and logarithmic model. The continuous deformation of the tunnel was primarily temperature dependent. In addition to the effect of temperature, the opening width also exhibited a strong influence on tunnel deformation. The span length gradually achieved a constant effect upon tunnel deformaiton as the opening width increased. The overburden thickness also exhibited an influence on convergence rate.
