The effect of microstructure on shear strength of saturated marine clays was investigated by conducting a series of consolidated-drained (CD), consolidated-undrained (CU) triaxial shear tests and
(PDF) The Undrained Shear Strength of Overconsolidated ClaysThe strength properties of two overconsolidated clays (Todi Clay and London Clay) are presented and the intact strengths are shown to be greater than the corresponding intrinsic strengths.
Department of Civil Engineering/ Engineering Faculty 18/02/2021 2 University of Sulaimani-College of Engineering-Civil Engineering Department Ch. 8:Shear Strength 18/02/2021 3 The shear strength of a soil mass is the internal resistance per unit area that the soil mass can offer to resist failure and sliding along any plane inside it. One must understand the nature of shearing resistance in
Experimental Study on the Deformation and Strength Initial shear stress and vibration frequency have significant effects on the deformation and strength characteristics of saturated clay. The larger the initial shear stress or the lower the vibration frequency is, the more sufficient the dynamic strain of soil develops and the fewer the number of cycles required to reach the same dynamic strain.
Porosity influence on the shear strength of granular Nov 01, 2000 · If the percentage by weight of the granular material in the granular materialclay mixture was >75%, the shear strength of the mixture was basically that of the granular material alone.
The impact of dominating clay mineral and cyclic wetting and drying on the cohesion and frictional strength behavior were described, and the following conclusions can be drawn:(1) For the as-compacted samples, the frictional and cohesion shear strength appeared to be affected by the clay mineral content. The cohesion increases with increase in the kaolin/montmorillonite content up to a maximum of about 70%
Shear Strength of Sand:Characteristics and Factors Soil Factors Affecting Shear Strength of Sand:The shear strength of cohesionless soils may be eed by r = tan (13.36) Factors affecting the shear strength of sands are the following:1. Particle Size:Gravels have higher friction angle than that of sands, which, in
Stress-Strain and Strength Characteristics of Silt-Clay Oct 10, 2012 · It is observed that the tested silt-clay soils are less compressible with increasing silt content during one-dimensional and isotropic compression tests. During drained and undrained triaxial tests, the normally consolidated soils at the same consolidation stress show larger values of stiffness and drained and undrained shear strengths with increasing silt content.
Dec 01, 2010 · Results show that improvements in shear strength of up to 100% could be realized for the Hemp reinforced specimens. The percent improvement increases with the fiber content up to a threshold value of 1.25% and differs depending on the magnitude of the water content used in compaction in reference to the optimum moisture content of the matrix clay.SOIL DEFORMATION AND SHEAR STRENGTH The shear strength of the clay soils tested was more closely related to the soil moisture suction and to the amount of shrinkage which occurred on drying than to the absolute dry bulk density. The influence of moisture content and spherical pressure on the
