During last 60 years many research studies have been conducted on calculation of shear strength of unsaturated soils and effects of matric suction on it. Several formulae are developed for predicting shear strength of unsaturated soils, based on strength tests on unsaturated soils. A variety of experimental techniques and laboratory equipment are used for unsaturated shear strength characterization. This study discusses the accuracy of shear strength prediction for unsaturated soils with three different formulae. The predicted shear strengths of three different soils for a wide range of suction, using these formulae are compared. And finally the dependency of accuracy of the best formula among the three investigated formulae on the net normal stress is investigated.

Estimation of lining thickness around circular shafts
Ozturk, H; Unal, E (2001-06-22)
In this paper, the broken zone developing, around a circular mine shafts and lining pressure is estimated by integrating the results of numerical analysis and the "rock-load height" equation derived from empirical analysis. During numerical modelling studies, the computer program FLAC(2D) was utilized. In order to estimate equivalent Mohr failure Envelope from the generalised Hoek Brown failure criterion, a new FISH function was written within FLAC(2D). Parametric studies were carried out by considering mRM...
Exponential Equation for Predicting Shear Strength Envelope of Unsaturated Soils
Ahmadi Naghadeh, Reza; Toker, Nabi Kartal (2019-07-01)
An exponential equation is introduced to predict the nonlinear variation of shear strength with matric suction for unsaturated soils. The proposed equation involves three constant parameters, two of which are effective shear strength parameters (i.e., phi ' and c '). The third parameter is the maximum capillary cohesion, c '' max, which is the maximum possible increase in shear strength due to matric suction. A procedure for the determination of c '' max from the soil-water characteristic curve (SWCC) is de...
Comparison of undrained shear strength by pressuremeter and other tests, and numerical assessment of the effect of finite probe length in pressuremeter tests
IŞIK, Nihat Sinan; ULUSAY, REŞAT; Doyuran, Vedat (2015-08-01)
There is a wide body of research reported in the literature which compare the undrained shear strength determined from various field and laboratory tests. The pressuremeter testing equipment and the related design techniques have been continuously refined. However, the undrained shear strength (S (u)) determined from the pressuremeter test (PMT) is generally higher than that obtained from other field or laboratory tests. In this study, numerical methods to consider the effects of length to diameter ratio (L...
Comparative study of soil water characteristic curve prediction methods
Ahmadiadli, Mohammad; Huvaj Sarıhan, Nejan; Toker, Nabi Kartal; Kürkçü, Mefküre Gamze (2012-06-30)
The soil-water characteristic curve (SWCC), which defines the relation between soil suction and water content, plays a key role in geotechnical studies of the unsaturated soils. Some researchers such as Brooks & Corey (1968), Van Genuchten (1982) and Fredlund& Xing (1994) have proposed curve fitting equations for SWCC. Fitting equations to the laboratory test data obtained from direct measurement of water content versus changes in matric suction is the most reliable method, but it is expensive and time cons...
Some remarks on the removal rates of H2S within the suboxic zone of the Black Sea
Gokmen, S; Basturk, O (1997-06-19)
This work constitutes an initial effort for studying the removal and/or oxidation rates of hydrogen sulfide at different surfaces of the suboxic zone of the Black Sea. The measurements were made by mixing waters from the suboxic zone (sigma(theta)=15.70-16.20) and from the upper layer of the anoxic zone (sigma(theta)=16.50). The half-life of H2S removal within the interior of cyclonic gyre was found to be twice that measured in the rim current region close to the Bosphorus northern exit, whereas the largest...
