摘要
We developed an icicle/frost heave prevention system aided by a heat pipe for railway tunnels. To evaluate the system, we installed test pieces in an existing tunnel and measured their temperatures. Furthermore, effects were confirmed through a numerical simulation of heat transfer using a one-dimensional unsteady-state model. On the basis of the results of field test and simulation, it is concluded that the developed system effectively prevents icicle/frost heave.
