Static and Dynamic Axial Response of Drilled Piers. II: Numerical Simulation
Publisher: American Society of Civil Engineers
Abstract: Realistic time history simulation of drilled pier/pile-soil systems under dynamic and static loading is essential for the development of effective performance-based earthquake designs of deep foundations. This paper presents ...
Direct Estimation of Yield Acceleration in Slope Stability Analyses
Publisher: American Society of Civil Engineers
Abstract: In conventional slope stability analyses, the yield acceleration is traditionally estimated by trial and error. This approach becomes unwieldy when hundreds or thousands of iterations are required in rigorous probabilistic ...
Method for Determination of Hydraulic Conductivity in Unsaturated Porous Media
Publisher: American Society of Civil Engineers
Abstract: A new procedure for in situ determination of saturated hydraulic conductivity of an initially unsaturated soil is proposed. The procedure is based on the measurement of the rise of a ground‐water mound in an initially ...
Discussion by “<i>Strain Compatibility Design Method for Reinforced Earth Walls</i>” by Ilan Juran and Chao L. Chen (April, 1989, Vol. 115, No. 4)
Publisher: American Society of Civil Engineers
Seismic Earth Pressures on Cantilever Retaining Structures
Publisher: American Society of Civil Engineers
Abstract: An experimental and analytical program was designed and conducted to evaluate the magnitude and distribution of seismically induced lateral earth pressures on cantilever retaining structures with dry medium dense sand ...
Stability of Steep Slopes in Cemented Sands
Publisher: American Society of Civil Engineers
Abstract: The analysis of steep slope and cliff stability in variably cemented sands poses a significant practical challenge as routine analyses tend to underestimate the actually observed stability of existing slopes. The presented ...
Geotechnical Properties of Cemented Sands in Steep Slopes
Publisher: American Society of Civil Engineers
Abstract: An investigation into the geotechnical properties specific to assessing the stability of weakly and moderately cemented sand cliffs is presented. A case study from eroding coastal cliffs located in central California ...
Deformation Characteristics of Reinforced Sand in Direct Shear
Publisher: American Society of Civil Engineers
Abstract: A series of direct shear laboratory tests was performed in order to examine the mechanism of shear zone development in reinforced sands and to quantify their deformation characteristics. Six types of reinforcements were ...
Closure to “<i>Deformation Characteristics of Reinforced Sand in Direct Shear</i>” by Scott E. Shewbridge and Nicholas Sitar (August, 1989, Vol. 115, No. 8)
Publisher: American Society of Civil Engineers
Deformation‐Based Model for Reinforced Sand
Publisher: American Society of Civil Engineers
Abstract: A closed‐form solution for determining the development of tension in soil reinforcements is incorporated in a rigid‐plastic soil model. The model accounts for the plastic work to deform the soil and the elastic work to ...
