The shear strength of an unsaturated soil is written in terms of two independent stress state variables which show the transition from a saturated to an unsaturated state. The independent roles of changes in total stress and changes in pore-water pressure are easily visualized in the formulae. ...
In this paper,the swelling pressure and strength of two typical expansive soils respectively collected from Heishan of Liaoning Province and Meishan of Nanjing are systemically investigated using the methods of conventional soil tests in order to understand its physical and mechanical properties and ...

The concept of terminative water content is suggested and the calculation formula for shear strength of unsaturated loess is obtained based on the experimental data. 展开 关键词: unsaturated loess structural strength shear strength water content ...
Shear Strength Parameter In subject area: Engineering Soil strength is generally expressed in terms of shear strength parameters of the soil. From: Mooring System Engineering for Offshore Structures, 2019 About this pageAdd to MendeleySet alert Discover other topics ...
Accurately determining the shear strength of structural planes is crucial for evaluating the stability of rock masses. The shear test using the sawtooth structural plane usually captures the main influencing factors of its shear characteristics. In this
China 3 Institute of Tunnel and Underground Engineering, Hohai University, Nanjing 210098, China * Correspondence: liuxin100@hhu.edu.cn Abstract: While post-grouting is frequently reported to improve the engineering performance of piles, the shear strength of the soil around piles is not well unders...
The interface shear strength is generally reported by fitting a linear Mohr–Coulomb failure envelope (defined by the apparent adhesion, c, and interface friction angle, δ) to shear data measured at a range of confining pressures for peak and/or residual conditions. ...
Shear strength parameters play a crucial role in the design and construction of rock slopes, underground openings, tunnels, excavations, and foundations. D
These components of shear strength do not have directional values, except the dilation angle. Thus, all cross-anisotropy relates to the variation of the angle of dilation obtained for different directions. This in turn is dependent on the particle fabric or structure in the soil. 3. Previous st...
