RISDesign of Dynamically Wind-Loaded Helical Piers for Small Wind Turbines
Publisher: American Society of Civil Engineers
Abstract: The expansion of alternative energy has created a demand for sustainable alternatives for wind turbine foundation design. This study investigates the proposed application of helical piers as foundations for guyed cables ...
Effects of Long-Term Dynamic Loading and Fluctuating Water Table on Helical Anchor Performance for Small Wind Tower Foundations
Publisher: American Society of Civil Engineers
Abstract: The application of this study is to use helical anchors as a foundation system for small wind tower
Scale Effects of Shallow Foundation Bearing Capacity on Granular Material
Publisher: American Society of Civil Engineers
Abstract: Scale effects of shallow foundation bearing capacity on granular materials were investigated to further evaluate the trend of decreasing bearing capacity factor,
Determining Intrinsic Compressibility of Fine-Grained Soils
Publisher: American Society of Civil Engineers
Abstract: Results of laboratory oedometer tests on reconstituted specimens of four clays prepared at different initial water contents, ranging from the liquid limit to 1.75 times the liquid limit, show that the intrinsic compression ...
General Model for the Uniaxial Tensile Strength Characteristic Curve of Unsaturated Soils
Publisher: ASCE
Abstract: Characterization of tensile strength is critical to investigate the influence of desiccation and tensile cracks on the structural integrity of natural and artificial earthen structures and slopes. Although several models ...
Using Fractal Geometry Theory to Quantify Pore Structure Evolution and Particle Morphology of Stabilized Kaolinite
Publisher: American Society of Civil Engineers
Abstract: Soil improvement via cement-based stabilizers is often necessary to improve the workability and strength of problematic soils. However, understanding the underlying mechanisms of the stabilization process merits further ...
Influence of Clod-Size and Structure on Wetting-Induced Volume Change of Compacted Soil
Publisher: American Society of Civil Engineers
Abstract: Volume changes due to wetting may occur in naturally deposited soils as well as earthen construction (e.g., compacted fills or embankments). Depending on the stress level, some soils exhibit increase in volume upon wetting ...
Educational Module to Demonstrate the Seismic Behavior of Piles in Improved and Unimproved Soft Soils
Publisher: American Society of Civil Engineers
Abstract: This engineering educational module on the behavior of piles in soft clays during earthquake loading sought to introduce engineering as a viable career to eighth graders and teach students how geotechnical engineers design ...
Centrifuge Modeling of Laterally Loaded Pile Groups in Improved Soft Clay
Publisher: American Society of Civil Engineers
Abstract: A series of centrifuge tests were performed to investigate the behavior of laterally loaded pile groups in improved and unimproved soft clay. The soil profile consisted of four lightly overconsolidated clay layers overlying ...
