Repeated load triaxial testing of a silty clay

Géotechnique, 1975
Repeated load triaxial tests have been carried out on samples of Keuper marl reconstituted from a slurry. The stress history of each sample was controlled and overconsolidation ratios between 2 and 20 were used. The repeated load tests were carried out undrained and involved the application of cyclic deviator stresses at a frequency of 10 Hz and the ...

Small-strain dynamic properties of silty clay stabilized by cement and fly ash

, 2020
This study examines the small-strain dynamic properties of cement-stabilized silty clay (CSC) and cement-fly ash-stabilized silty clay (CFSC). A series of resonant column tests were performed to investigate the effect of confining pressure, binder ...

Strength and deformation characteristics of silty clay under frozen and unfrozen states

Cold Regions Science and Technology, 2020
Frost damage of soil foundations of engineering structures is controlled by mechanical properties of soil under frozen and unfrozen states, existing widely in cold regions such as Genhe area that is termed as the “pole of cold” in China.

Tillage Implement Forces Operating in Silty Clay Loam

Transactions of the ASAE, 1996
Regression equations for draft forces of a tandem disk, chisel plow, and field cultivator were developed based upon travel speed and tillage depth. The effect of tillage depth on the draft of the tandem disk, chisel plow and field cultivator was observed to have more influence than travel speed.

An anisotropic bounding surface elastoplastic constitutive model for frozen sulfate saline silty clay under cyclic loading

, 2020
To study the mechanical properties of frozen saline soil under cyclic loading, the cyclic tri-axial compressive experiments of 36 samples are performed for frozen saline silty clay with 0.0, 0.5, 1.5 and 2.5% of Na2SO4 contents at the temperature of −6 ...

Strength properties of nano-MgO and cement stabilized coastal silty clay subjected to sulfuric acid attack

Marine georesources & geotechnology, 2020
The characteristics of nanometer magnesium oxide (nano-MgO) admixed cement in the treatment of clay were studied in direct shear tests. The chemical resistance of the admixed clay cement was investigated by soaking specimens in sulfuric acid solution ...

Thermodynamics of interaction of lindane on silty loam and silty clay loam Indian soils

Journal of Environmental Science and Health, Part B, 1996
Abstract Interaction of lindane with silty loam and silty clay loam soils was studied in batch tests at 23, 30 and 37° C. Sorption experiments were carried out at four concentrations and for varying time of contact upto 72 hours. This was followed by desorption studies. No desorption was observed. The sorption data was analysed using sorption equations

Assessment of geotechnical variability of Songdo silty clay

Engineering Geology, 2012
Abstract The reliable estimation of the coefficient of variation (COV) and probability density function (PDF) is required to characterize the uncertainty and variability of soil properties. An outlier test, a randomness test (runs test), and a Goodness-of-Fit test are performed in sequence to determine the reliable COVs and PDFs of soil properties ...

Rates of seasonal creep of silty clay soil

Quarterly Journal of Engineering Geology, 1975
Summary Profiles of displacement caused by seasonal creep of an expansive silty clay soil were measured at several times of the year with a tiltmeter and flexible pipes installed in two areas near Stanford University in central California. The displacement profiles typically are convex upward and net creep displacement at the ground surface ...
