Strength Characteristics of Nonpenetrating Joint Rock Mass under Different Shear Conditions
Advances in Civil Engineering, 2020 The mechanical property of jointed rock mass is an important factor to be considered in the analysis, evaluation, and design of actual rock engineering. The existence of joints threatens the stability and safety of underground engineering projects built ...

Modification of linear regression method for rock shear strength parameters under triaxial condition
Rock and Soil Mechanics, 2022 The triaxial strength envelope of rocks is usually nonlinear, and the shear strength parameters obtained by the linear regression method (LRM) are highly sensitive to confining pressure.

Modified Triaxial Apparatus for Shearing-Infiltration Test
Geotechnical Testing Journal, 2001 Abstract A triaxial apparatus was modified and developed for performing shearing-infiltration tests under saturated and unsaturated conditions. Miniature pore-water pressure transducers were installed at different heights of the soil specimen for pore-water pressure measurement.

Numerical simulations of triaxial shearing-infiltration tests
Soils and Foundations, 2018 Abstract The failure of steep slopes during rainfall is commonly associated with a decrease in matric suction in the unsaturated soil zone above the water table. The shear strength characteristics of residual soil under water infiltration have been studied in the laboratory using unsaturated triaxial tests.

Behaviour of a loose silty sand under static and cyclic loading conditions [PDF]
E3S Web of Conferences, 2019 In recent years, considerable progress have been made in the study of liquefaction and flow failures with the introduction of the notion of steady-state of deformation and “collapse” envelope.

Comparison of sand liquefaction in cyclic triaxial and simple shear tests
Soils and Foundations, 2021 The liquefaction resistance and correction factors Kσ and Kα of Nakdong River sand obtained from cyclic triaxial (CTX) tests were compared with those determined by cyclic simple shear (CSS) tests to ascertain the importance of the reduction factor Cr and correction factors Kσ and Kα in liquefaction evaluations, especially in view of the lack of ...
