Assessment of Peak/Residual Failure Envelopes of Clayey Soil via Suction-controlled Ring Shear Testing [PDF]

E3S Web of Conferences
A thorough experimental program has been undertaken to assess the suction-controlled peak and residual shear strength responses of statically compacted, moderate plasticity clayey soil over a relatively wide range of suction states.

A CRS oedometer cell for unsaturated and non-isothermal tests [PDF]

, 2019
Research into the thermo-hydro-mechanical (THM) behavior of unsaturated soils and the effect of strain rate on their mechanical responses requires employment of advanced laboratory testing systems and procedures as well as protocols of correcting the ...

Preliminary Analysis on Matric Suction for Barren Soil

IOP Conference Series: Materials Science and Engineering, 2016
Abstract Most research conducted on slope failures can broadly be attributed to the convergence of three factors, i.e. rainfall, steepness of slope, and soil geological profile. The mechanism of the failures is mainly due to the loss of matric suction of soils by rainwater.

An Active Control System for Matric Suction Measurement

Soils and Foundations, 2009
Matric suction is an important stress state parameter in unsaturated soil mechanics. Many studies have been carried out in the past to determine the matric suction through direct and indirect methods. Direct measurement of matric suction has been proven possible with high-suction tensiometer; however high-suction tensiometers are still susceptible to ...

Determination of Soil-Water Characteristic Curves of Unsaturated Sandy Soils Using Membrane Filter with Stainless Wire Mesh [PDF]

, 2009
Soil-water characteristic curve (SWCC) is an important soil function in an unsaturated soil mechanics field for design and analyses of any unsaturated earth structures. Determination of SWCC is not easy and more so time consuming. Generally, ceramic disc

Matric Suction Creep Characteristics of Reticulated Red Clay

KSCE Journal of Civil Engineering, 2018
Matric suction creep is the creep of unsaturated soil caused by loading constant matric suction. Matric suction creep characteristics of reticulated red clay with constant net confing pressure and step-loading matric suction was studied using stress-controlling unsaturated triaxial test apparatus.

Analysis of the suction evolution during direct shear test in a silty sand soil [PDF]

E3S Web of Conferences, 2020
Shear strength of soils is one of the essential parameters for analysing and solving divers geotechnical problems (e.g. the bearing capacity of shallow footings pile foundations, slope stability and earth embankments).

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

, 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 ...

Study on the stress path dependency of collapse behavior of Gorgan loess implementing unsaturated oedometer devices

E3S Web of Conferences, 2016
Collapsible soils such as loess are particular types of problematic soils, whose collapse potential have caused severe damages to the buildings and structures.

Numerical analysis of matric suction effects of tree roots [PDF]

Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2006
The use of native vegetation in the coastal regions of Australia has become increasingly popular for stabilising railway corridors built over expansive clays and compressive soft soils. The tree roots provide three stabilising functions: (a) they reinforce the soil; (b) they dissipate excess pore pressures; and (c) they establish sufficient matric ...
