Experimental study on the displacement evolution of rock interface friction slip based on crack

open access: yes矿业科学学报, 2021
To study the further evolution characteristics of the fracture plane or structural plane after rock failure, the granite was chosen and prepared as double penetration crack samples, and the friction sliding tests were conducted using twin-shear model ...

Field investigation of deformation characteristics and stress mobilisation of a soil slope [PDF]

open access: yes, 2015
Stress mobilisation and deformation of a slope are important for engineers to carry out reliable design of retaining systems. However, most case histories reported mainly on the response of pore-water pressure (PWP), whereas knowledge about the stress ...
