The shear strength of unsaturated soils
Canadian Geotechnical Journal, 1978The shear strength of an unsaturated soil is written in terms of two independent stress state variables. One form of the shear strength equation is[Formula: see text]The transition from a saturated soil to an unsaturated soil is readily visible. A second form of the shear strength equation is[Formula: see text]Here the independent roles of changes in ...

Shear strength of coarse fragmental soils
Hydrotechnical Construction, 19691. The construction of high earth and rock dams requires that investigators obtain exact data on the shear resistance and deformative properties of coarse-fragmental soils. 2. Investigations carried out in recent years here and abroad have made it possible to establish the following: a) The angle of internal friction of ...

Residual shear strength of soils
Bulletin of the International Association of Engineering Geology, 1978The relations between the residual shear strength of soils and their index properties have been proved. Best correlation appeared to be between the residual shear strength and the index of plasticity. However, the correlation is not enough to enable the simple index tests to be substituted for the complex residual shear tests.

Shear strength is a very important property of soils. The concept is used by geotechnical engineers in estimating the bearing capacity of foundations and in assessing the stability of retaining walls, slopes, and embankments and the design and construction of highway and airfield pavements.

Shear Strength Criteria for Unsaturated Soils
Geotechnical and Geological Engineering, 2009Shear strength is one of the fundamental properties of unsaturated soils. It has been found to change with matric suction. Various shear strength equations have been proposed for predicting the shear strength versus suction relationship for unsaturated soils.

Shear may be defined as the tendency of one part of a soil mass to slide with respect to the other. This tendency occurs on all planes throughout the soil mass. The singular plane of interest, however, is the plane of potential failure, called the plane of rupture.

Shear strength of unsaturated soil interfaces
Canadian Geotechnical Journal, 2009Unsaturated soil interfaces exist where unsaturated soil is in contact with structures such as foundations, retaining walls, and buried pipes. The unsaturated soil interface can be defined as a layer of unsaturated soil through which stresses are transferred from soil to structure and vice versa. In this paper, the shearing behavior of unsaturated soil

Shear Strength of Soils on Slopes
SAE Technical Paper Series, 1964<div class="htmlview paragraph">Surface mobility is one of the most critical problems in design of a lunar roving vehicle, and tests of vehicle models in frictional soils were initiated early in our program. Tests on grades produced anomalous results, and it was found that conventional assumptions for predicting grade performance from results of ...

The Shear Strength Behavior of Two Peaty Soils
Geotechnical and Geological Engineering, 2005This paper presents experimental research concerning the shear behavior of two types of Italian peat, one normally, the other over consolidated. Organic soils are characterized by very high compressibility and high fiber content; two features that give rise to several problems during laboratory tests.
