【 摘 要 】

The frost heave pattern and the frost heave design of the large channel in the cold area are still not yet fully solved. In this study, based on the large channel of Hada Mountain Water Conservancy Project, the in-situ large-scale thermal protection slope test was carried out, and the frost heave deformation law of the thermal dewatering slope was obtained. The results have certain guiding significance for the frost heave design of the large channel in the cold area.
