CONSTANT VOLUME SHEAR TESTS ON COMPACTED SILTY SOIL

Assessment of the Mechanical Properties of Sisal Fiber-Reinforced Silty Clay Using Triaxial Shear Tests

Fiber reinforcement is widely used in construction engineering to improve the mechanical properties of soil because it increases the soil's strength and improves the soil's mechanical properties. However, the mechanical properties of fiber-reinforced soils remain controversial. The present study investigated the mechanical properties of silty clay reinforced with discrete, randomly distributed ...

Micromechanics of soil responses in cyclic simple shear tests

Offshore wind turbine (OWT) foundations are subjected to a combination of cyclic and dynamic loading arising from wind, wave, rotor and blade shadowing. Under cyclic loading, most soils change their characteristics including stiffness, which may cause the system natural frequency to approach the loading frequency and lead to unplanned resonance and system damage or even collapse. To investigate...

Behavior of Compacted Lime-soil Columns

This study presents the results of large scale laboratory model tests to investigate the behavior of Compacted Lime – Well-graded Soil (CL-WS) rigid stone columns in soft soils. The  unit cell idealization is used for construction of composite specimens by evaluating the influence of different parameters such as the diameter of the column (D), the slenderness ratio (L/D) and the area ratio (Ar)...

Winter Wheat Growth in Artificially Compacted Soil

Strength-Flow Parameters of Loose Silty Sands From Piezocone Tests

Piezocone penetration tests with dissipation phases are particularly useful for geotechnical site characterization. They also provide three independent readings with depth from a single sounding as well as time-rate information. In past investigations, only silty sands with specific silt content have been tested and complete sets of tests have not been conducted to evaluate the influence of dif...
