Investigation for the deformation of embankment underlain by warm and ice-rich permafrost

The purpose of this study is to investigate the settlement of the embankment constructed in warm and ice-rich permafrost (WIRP) region along the Qinghai–Tibetan Railway (QTR). In this investigation, an in-situ experiment for the thermal regime under this embankment and for the settlement of the embankment is proposed. The data illustrate that the thicker the embankment fill, the thicker the WIRP layer under the embankment, and the greater the...
