| description abstract | This technical note presents an experimental study on the ventiduct embankment in permafrost regions of the Qinghai-Tibet Railroad. Two experiments were conducted in a test box and they were designed with similarity theory. Some preliminary results are given to describe the temperature regime properties of the embankment, and the temperature differences between the ventiduct embankment and the normal embankment are compared. Results showed that the ventiduct embankment has a good cooling effect; it has a faster cooling rate than the normal embankment; the range of influence of a single duct can reach one duct diameter; the temperature distribution of the ventiduct embankment is asymmetric along the wind direction. | |
