Effects of Temperature on Residual Shear Strength of Cohesive Soils
… soil responses, the effects of temperature on residual shear strength of soils are not well understood. Previous studies on temperature effects on residual shear strength show some contradictory findings that might be attributed to the sample's mineralogical composition and the testing …

Probabilistic Post-Liquefaction Residual Shear Strength Analyses of Cohesionless Soil Deposits: Application to the Kocaeli (1999) and Duzce (1999) Earthquakes
… natural soil slopes, and mine tailings. The residual or liquefied shear strength of the liquefiable soils is a very important parameter when evaluating stability and deformation of level and sloping ground. Current procedures for estimating the liquefied shear strength are based on extensive …

Seismic Stability of Slopes in Sensitive Cohesive Soils
The use of the field vane shear test for measuring the undrained peak and residual shear strength was also reviewed. A correction factor for use of the vane shear strengths in seismic stability evaluations was proposed. The validity of the proposed correction factor was verified using the Fourth …

An Experimental Study of the Dynamic Behavior of Slickensided Surfaces
When a clay soil is sheared, clay particles along the shear plane become aligned in the direction of shear, forming "slickensided" surfaces. Slickensided surfaces are often observed along the sliding plane in field landslides. Because the clay particles along a slickensided surface are already …

Meaning, measurement, and field application of fully softened shear strength of stiff clays and clay shales
The mobilized shear strength in the failure of natural and cut slopes is important for design and stability evaluation. The intact shear strength is rarely available at the time of first-time slope failures. It is generally accepted that only residual shear strength is available for the reactivated …

The relationship between slope stability and pore-water pressure in highly plastic clay in the Carrot River Basin
… an embankment constructed between 1990 and 1992. Residual shear strength parameters, Φᵣ' = 7.6° with c' = 0 were determined for three landslides by back analysis. Laboratory tests showed Φᵣ' ranged from 6.0 to 9.1 °. Pore-water pressure distributions were characterized with models of steady state …

Soil and Site Characterization Using Electromagnetic Waves
… proper knowledge and understanding of (1) the strength, (2) the fluid flow properties, and (3) the stress-deformation behavior of the earth materials. These important engineering properties are primarily determined by the components and structure of a soil, which also dictate the soil's …

Residual strength of corroded reinforced concrete beams.
… none addresses the problems associated with the residual strength of reinforced concrete beams exhibiting both main and shear reinforcement corrosion simultaneously. The aim of this research, therefore, was to determine the residual strength of corroded reinforced concrete beams where various …

Lime treatment to improve frictional resistance and stability of stiff clay slopes
… cement or other stabilizers to the potential shear zone or along the pre-existing slip surface of reactivated landslides is an alternative to increase the stability and reduce the rate of movement. The effectiveness of lime treatment of soils has been commonly evaluated in terms of increased …

The Residual Strength of Liquefied Soil
… failure. To determine flow slide potential, the residual strength of liquefied soil is needed. However, this is an extremely difficult parameter to estimate for soil deposits due to spatial variability of soil properties, potential for the formation of water films, the intermixing of soils, and …

Analysis and behavior of preexisting landslides
The selection of shear strength parameters for the design and repair of landslide is important and difficult. Skempton (1964) concludes that if a failure has already occurred in clayey soils, any subsequent movement along the preexisting slip surface will be controlled by the drained residual …

Movement of landslides in stiff clays and clay shales
… slides with part of the slip surface at the residual condition. The load-controlled drained and undrained laboratory test data on undisturbed and remolded soft- to stiff- clays, reported in the literature, were analyzed. An empirical correlation for secant residual friction angle for a wide …

Shear Strength Assessment of Corrosion-Damaged Prestressed Concrete Girders
… Extensive research has focused on the flexural strength of corroded prestressed concrete girders. This research studies the shear strength of corroded prestressed concrete girders which can, then, be expanded further to evaluate the possible retrofitting techniques for restoring, or enhancing, …
