A Calibration Chamber for Cohesive Soils

Geotechnical Testing Journal, 1988
Abstract The paper describes the design and performance of a calibration chamber system for testing in-situ test devices in cohesive soils. Techniques for preparing “undisturbed” clay specimens from a slurry and consolidating them under zero lateral strain K0 conditions are presented.

Fractal Representation of Soil Cohesion

Journal of Geotechnical and Geoenvironmental Engineering, 1999
Evaluation of soil cohesion is usually based on measurements made on laboratory-scale samples. Some previous studies point out a decreasing trend in cohesion as the test specimen size increases. Although this trend is, in general, attributed qualitatively to fractures and macropores associated with larger samples, no rational basis has been put forth ...

Uplift Resistance of Cohesive Soils

Journal of the Geotechnical Engineering Division, 1977
Effects of vertical uplift forces on circular anchors in purely cohesive soils are considered. Model tests indicate a general type of ultimate uplift failure in shallow anchors, occurring by yielding above and below the anchor due to shear and tensile stresses and cracking in the soil. Existing shallow anchor theories, although in substantial agreement

Modelling of Cohesive Soils: Soil Element Behaviors

2017
The strain space multiple mechanism model, which was originally developed for the cyclic behavior of granular materials such as sand, is adapted to idealize the stress–strain behavior of clay under monotonic and cyclic loads. Compared to the conventional elasto-plastic models of the Cam-clay type, advantages of the proposed model include (1) the ...

Pile-Soil System Response in a Cohesive Soil

1969
This paper presents an investigation into the loading response of a saturated, cohesive soil medium associated with a pile-soil system. An instrumented test pile was driven in order to determine the adequacy with which proposed theories describe the field response of a pile-soil system. The test pile was a 50-ft-long 16-in.-diameter steel pipe in which

Dynamic strength of cohesive soils

Soil Mechanics and Foundation Engineering, 1997
A mathematical model and procedure for its practical use, which are intended for determination of the dynamic ultimate strengths of cohesive soils (clays, clayey loams) under external dynamic (impact) loads, the duration of which is reckoned in tenths and hundredths of a second, are proposed.

A Rheological Study of Cohesive Soils

1972
An attempt has been made to describe the mechanistic behavior of remolded and undisturbed soils by application of the principles of rheology. This was accomplished by approximating and comparing the data obtained from transient creep tests and relaxation tests to the mathematical behavior of mechanical impedance models.

Vertical Slope in Cohesive Soil

2017
A classical problem of soil mechanics is the case of a vertical cutoff in a purely cohesive material (\(\phi =0\)), as occurs when making a vertical excavation, or a vertical slope. The problem to be considered in this chapter is the determination of a lower bound or an upper bound for the maximum possible height \(h_{c}\) of the slope, for a material ...

Trench stability in cohesive soil

2011
Trench is connected to very narrow and deep excavation filled with bentonite suspension. This paper presents estimation of its stability in cohesive soil. The stability is assessed by two calculation methods. The first involves the equilibrium of forces acting on the rigid wedge.
