Shear strengthSilty claysA comprehensive laboratory program was carried out on specimens trimmed from 152 mm diameter piston samples of a soft silty clay and a varved clay at a tunnel site in Thunder Bay. Results of conventional triaxial tests as well as special tests for the determination of ...
In this paper, the main focus is on the changes in soil strength due to internal erosion. A series of one-dimensional upward seepage tests at a constant water head is performed to cause internal erosion in a soil sample by controlling the three variable parameters, namely (a) the fine ...
The shear strength, Sh, of the sample can be described by Coulomb’s equation: (2.1)Sh=ch+ph tanϕh The intercept ch is commonly known as the cohesion and φh is defined as the angle of internal friction. It should be noted that the parameters ch and φh depend on the type of ...
The calculated pre-consolidation stress and structural yield strength of the granite residual soil are similar, indicating a phenomenon that resembles over-consolidation in the granite residual soil. This is fundamentally different from the mechanism of conventional over-consolidation in soil. It is also...
Fragments which can be disintegrated with gentle finger pressure are characteristic of silty materials of low plasticity. Thus, in generally, fine-grained materials with relatively high dry strength are clays of high plasticity and those with relatively little dry strength are predominantly silts. ...
induced calcite precipitation (MICP) for controlling the swelling-shrinkage behavior and improving the shear strength of expansive soil. An attempt was made to develop an effective procedure to culture the indigenous bacteria for treating clays with varying plasticity and improve their engineering ...

In addition to other strains of bacteria, cyanobacterium inoculation in soil has demonstrated in the long run that it has a greater benefit on the structure and parameters of soil. They are important for soil surface stabilization, fundamentally because of the production of EPS. During arid conditi...
Moderate to strong ground shaking can create large excess pore water pressures in these soils, which temporarily decrease the effective stress and shear strength, which leads to strength loss, excessive settlements, lateral spreading, and other damages. The most common of sensitive clays are the ...
A study was undertaken to investigate the shear strength parameters of treated sands reinforced with randomly distributed glass fibers by carrying out dire... L Bouaricha,AD Henni,L Lancelot - 《Studia Geotechnica Et Mechanica》 被引量: 1发表: 2017年 Effect of Moisture Content and Wet–Dry Cycl...
