IMPLEMENTATION AND VALIDATION OF A HYDRO-MECHANICAL ELASTOPLASTIC CONSTITUTIVE MODEL FOR FULLY COUPLED ANALYSIS OF UNSATURATED SOILS
(2017-05)
Unsaturated soils are commonly encountered in natural soil deposits above the ground water table and in civil infrastructure construction as compacted soils. In earthquake prone areas, problems arise from dynamic loading ...
INFLUENCE OF HYDRAULIC HYSTERESIS ON THE MECHANICAL BEHAVIOR OF UNSATURATED SOILS AND INTERFACES
(2010)
Unsaturated soils are commonly widespread around the world, especially at shallow depths from the surface. The mechanical behavior of this near surface soil is influenced by the seasonal variations such as rainfall or ...
Novel, low-cost aluminum (hydr)oxide based materials for fluoride-impacted drinking-water: Batch and column studies
(2016-05)
Simple aluminum (hydr)oxides and layered double hydroxides were synthesized using common chemicals and equipment by varying synthesis temperature, concentrations of extra sulfate and citrate, and metal oxide amendments. ...
A bounding surface model for cyclic response of cement-improved clays
(2018-05-11)
The use of chemical stabilization of soft soils to achieve increased strength and decreased compressibility for subgrade and site improvement applications is a well-documented and accepted practice in geotechnical engineering. ...
IMPACT OF MOISTURE CHANGES IN UNSATURATED SOIL ENGINEERING APPLICATIONS
(2016-12-16)
The mechanical and hydraulic properties of soil above the groundwater table change due to unsaturated conditions. While common, considering soil to be saturated as a simplifying assumption in the design of many important ...
Shear Performance of Non-Traditional Concrete
(2018-08-02)
Concrete is the second most consumed material in the world, second only to water. Concrete has been around in different forms for centuries, and science and technology continually push the previously believed limits. Two ...
CHARACTERIZING UNCERTAINTY OF A HYDROLOGIC MODELING SYSTEM FOR OPERATIONAL FLOOD FORECASTING OVER THE CONTERMINOUS UNITED STATES
(2015)
The purpose of this work was to study the macro scale patterns of simulated streamflow errors in order to characterize uncertainty in a hydrologic modeling system and establish the basis for a probabilistic forecasting ...
Characterization of the iron sulfide oxidation products formed during reductive dechlorination of chlorinated aliphatic contaminants
(2016-05)
The overarching objective of this research is to investigate the transformation of iron sulfide, mackinawite (FeS), in contaminated environments. A special research focus is to investigate the FeS oxidation products formed ...
INVESTIGATION OF THE HYDROLOGY, FLUVIAL GEOMORPHOLOGY, AND SEDIMENT TRANSPORT IN THE LAKE THUNDERBIRD WATERSHED IN CENTRAL OKLAHOMA
(2015-05-08)
As human population continues to rise, an ever increasing burden is being placed on earth’s water resources. Between 1950 and 2010, the world’s population increased from 2.6 billion to almost 7 billion, and the population ...
A STUDY ON UNSATURATED SOIL-GEOTEXTILE INTERFACE STRENGTH USING MULTI-SCALE LABORATORY TESTS
(2014-12-12)
The performance of marginal soils and their interface with geosynthetic reinforcement can be complex under construction or service loading conditions and may include excessive deformations and loss of strength as a result ...
