Response of unsaturated soils constitutes an important consideration for many problems in geotechnical engineering. The main objective of this study is to understand coupling hydro-mechanical behavior of the unsaturated reconstituted specimens from slurry and moist-tamped compacted specimen, and to develop practical and cost-effective testing equipment and procedure. The innovations that will be put forth by this study will make the unsaturated soil mechanics more accessible and appealing to those practical engineers working. A prediction type exponential equation is introduced to predict the shear strength of the unsaturated soil. Equation involves three constant parameters. Two of which are effective shear strength parameters (i.e. ϕ́ and ć can be determined through conventional saturated shear strength tests). The third parameter is ultimate shear strength.

Prediction of swelling behavior of expansive soils using modified free swell index, methylene blue and swell oedometer tests
Jaleh Forouzan, Amir; Çokça, Erdal; Department of Civil Engineering (2016)
Expansive soils are recognized as problematic soils that impose several challenges for civil engineers. Such soils undergo significant volume change in case water penetrates into them, and they shrink as they lose moisture. Lightly-loaded engineering structures such as pavements, single story buildings, railways and walkways may experience severe damages when they are founded on such soils. Determination of expansive soils and quantifying their swelling potential and pressure caused by their expansion are e...
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...
DETERMINATION OF UNSATURATED SOIL PROPERTIES FROM SIMPLIFIED EXPERIMENTAL PROCEDURES
Kenanoğlu, Melih Birhan; Toker, Nabi Kartal; Department of Civil Engineering (2023-1-27)
Unsaturated soil mechanics provides theoretical basis to researchers and practitioners for the solution of various geotechnical engineering problems. The implementation of developed theories and experimental techniques into engineering practice is, however, questionable. The development of simple and rapid experimental procedures that are compatible with existing theoretical models could be beneficial in this regard. In this study, a complete framework of practical procedures for obtaining unsaturated...
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...
Replication of geomembrane interfaces using 3d printing (fused deposition modelling) technique
Uragan, Semkan; Huvaj Sarıhan, Nejan; Department of Civil Engineering (2020-12-22)
Geomembrane – soil interface is a critical consideration in geotechnical engineering applications such as liners and covers in landfills, canals or mine tailing dams. In some cases, lack of sufficient shear strength in these interfaces leads to poor performance, uneconomical design (such as requiring a longer geomembrane in an anchor trench), or may even lead to failure. To eliminate such problems, geometrical features known as asperities (or protrusions) are used on the geomembrane's interfacing faces. The...
