Abstract Terzaghi’s consolidation theory assumes strain in soil due to applied overburden pressure is small, and permeability and thus the coefficient of consolidation (Cv) remain constant during c...

Abstract Lignocellulosic biomass material sourced from plants and herbaceous sources is considered as a prospective feedstock of inexpensive, potentially carbon-neutral energy. Lignocellulosic biomass is structurally built on cellulose, hemicellulose, and lignin, which are present in varying concentrations based on the feedstock type and play distinct and not well understood mechanical functions in the flow behavior. The frictional characteristics of lignocellulosic biomass particulates influenc...

Traditional grain size distribution measurement techniques assume that the measured particle diameters are of individual grains. However, for suspended particulate materials, particles may be dispersed or associated in flocs. Further, particle-level associations depend on the surrounding fluid chemistry, which may change over time. The purpose of this study is to compare two different methods of grain size analysis for detecting particle and floc sizes in suspensions of fine coal refuse (FCR): h...

Abstract The stability of impounded slurry materials in part depends on the potential for flow and undrained shear strength. The purpose of this study is to investigate the effect of an added flocculant on the flow behavior and undrained shear strength of fine coal refuse (FCR). Specimens were formed from fresh FCR slurry samples obtained from an active impoundment slurry discharge pipe, as well as solids recovered from the same slurry mixed with either distilled water or a dispersant solution. ...

Abstract Natural slopes are often observed to have a concave, convex, or a combination concave/convex profile, yet constructed slopes are traditionally designed with planar cross-sectional geometry...

Abstract. While manmade slopes are traditionally constructed with planar cross-sections, natural stable slopes are usually curvilinear with significant concavity of the profile. This concavity occurs as a result of evolutionary processes in which rain-driven erosion and sediment transport are balanced through slope shape adjustments. At the point of equilibrium, a relatively steady concavity with a uniform erosion rate is observed over time. Nevertheless, a true equilibrium state is possible onl...

AbstractThe piling framed retaining wall (PFRW) is an innovative earth-retention system applicable for soils underlain by rock, which is ideal for applications where only limited right-of-way is available or adjacent structures limit the use of tieback anchors. Two PFRWs were successfully built along the I-40/I-75 corridor in Knoxville, Tennessee, with significant cost savings over traditional retaining wall designs. Although the walls were designed using conventional earth pressure theories, th...

AbstractThe growth of precision autoguidance systems on construction equipment suggests that nonplanar slopes and landforms now can be constructed readily. Slopes with concave cross sections not only appear more like natural slopes, but can also have superior stability and erosion resistance. Thus, it is desirable to have the description of concave slopes that provide mechanical stability for a given set of soil properties. In this paper, an approximate solution that defines the geometry of crit...
