Abstract: The geotechnical investigations were conducted on the Liuzhuang Mine main shaft tower ground freezing excavation site before and after the ground freezing when the ground was completely thawed. Different test methods were applied at the site and changes of the soil properties before and after the ground freezing were compared.
