High-Speed Undrained Ring Shear Test Dataset

This dataset is obtained through high-speed undrained ring shear tests and calculations based on a newly developed pore-water pressure model. The tests were conducted on the sliding zone from the Luanshibao landslide in Litang County, Sichuan Province, China. The experimental conditions include normal stresses of 200, 400, and 600 kPa, with shear speeds of 0.5, 5, and 50 cm/s. The study aims to reveal the evolution of pore-water pressure in the sliding zone of long-runout landslides during high-speed movement.
