Description
Haotian Guo and four co-authors model the forces on supports that hold a deep building pit through winter in frozen ground, in a 2024 study. In the Changchun area, pits dug in clay-rich soil sit open over winter while the ground freezes. Using room-temperature traits of wet soil misstates the loads, since cold changes the soil’s strength.
The team measured strength in lab tests on unsaturated soil, then built a pit model in simulation software from those values. In its natural state the local clay held a suction of 70 kilopascals, and its cohesion rose as temperature fell. They varied key traits to see which drove stress and bending of the supports. Model results matched field monitoring well, which validates the cold-soil approach.
