The effect of grain size, surface roughness, and joint compressive strength on shear strength along discontinuities of Hungarian sandstones [PDF]
, 2018 In this study, the joint shear strength of low-strength Hungarian sandstones of different grain size and surface roughness was investigated. The direct shear tests along discontinuities were performed under constant normal load.

Characterization of peak shear strength of rough rock joints using limited displacement multi-stage direct shear (LDMDS) tests [PDF]
E3S Web of Conferences, 2019 Current standard direct shear test methods for rock joints do not account for damage to the specimens' asperity profiles; tests require shearing of a single specimen to large displacements under successive normal stresses (the multistage test), or the ...

An Apparatus for In Situ Direct Shear Tests on Snow
Experimental Techniques, 2016 The article presents a prototype of a new device for measuring the shear strength of snow specimens in situ. The resistance to sliding of a snow slab on a mountain slope is a key parameter in snow mechanics. The proposed apparatus acts as a sampler, to obtain a nearly undisturbed specimen, and as a shear box, similar to those used in the laboratory ...

Shear strength of an unsaturated silty sand [PDF]
, 2011 This paper presents a series of direct shear tests performed on a silty sand at three different gravimetric water contents. The soil was sampled from test pits south of Ruedlingen in North East Switzerland, where a landslide triggering experiment was ...

Application of in situ direct shear device to shear strength measurement of rockfill materials
Water Science and Engineering, 2009 A simplified in situ direct shear test (DST) was developed for measuring the shear strength of soils in fields. In this test, a latticed shearing frame replaces the upper half of the shear box used in the conventional direct shear box test.

Interface shear characteristics of dredger fill and concrete using large size direct shear test
International Journal of Geo-Engineering, 2018 A large-size direct shear test was conducted to test the interface of dredger fill and concrete. The effect that concrete strength and the density of dredger fill have on the properties of interface is then analyzed.
