    • Laboratory Modeling of Vibro‐Driven Piles 

      Michael W. O'Neill; Cumaraswamy Vipulanandan; Daniel Wong (American Society of Civil Engineers, 1990)
      TO better understand the factors influencing the driveability and bearing capacity of vibro‐driven piles, a large‐scale laboratory study was performed. The testing system consisted of a pressure chamber to simulate in situ ...

    • Behavior of Vibro‐Driven Piles in Sand 

      Cumaraswamy Vipulanandan; Daniel Wong; Michael W. O'Neill (American Society of Civil Engineers, 1990)
      Methods available for estimating the bearing capacity of piles installed with vibratory drivers are inadequate and do not explicitly incorporate important variables, such as soil parameters and in situ stresses. The influence ...

    • Influence of Clods on the Hydraulic Conductivity of Compacted Clay 

      Craig H. Benson; David E. Daniel (American Society of Civil Engineers, 1990)
      The hydraulic conductivity of a highly plastic, compacted clay soil is significantly influenced by the size of clods used in preparing the soil for compaction. For soil compacted dry of optimum, hydraulic conductivity is ...

    • System Reliability of Slope Stability 

      Yoneo Oka; Tien H. Wu (American Society of Civil Engineers, 1990)
      In stability problems, the failure probability associated with the critical slip surface is known to be smaller than that for the system that comprises all potential slip surfaces. The difference depends on the correlation ...

    • Consolidation and Permeability of Two Compacted Schist Saprolites 

      Olufemi Ogunsanwo (American Society of Civil Engineers, 1990)
      Saprolites derived from a mica schist and a quartz schist from southwestern Nigeria are compacted at three energy levels, namely 0.6 MNm/m

    • Settlement Analysis of Socketed Pile Groups 

      Y. K. Chow; J. T. Chin; Y. C. Kog; S. L. Lee (American Society of Civil Engineers, 1990)
      A numerical procedure is presented for the settlement analysis of group piles that penetrate an upper soil layer to socket into a firm bearing stratum of finite stiffness. An extensive parametric study is carried out to ...

    • Shear Stress‐Strain Curve Generation from Simple Material Parameters 

      Jean H. Prevost; Catherine M. Keane (American Society of Civil Engineers, 1990)
      The commonly used hyperbolic function is known to be deficient in accurately modeling failure even though it is easily fitted to the initial conditions. To correct that deficiency, a modified hyperbolic function which ...

    • Dynamic Response of Sand Reinforced with Randomly Distributed Fibers 

      Mohamad H. Maher; Richard D. Woods (American Society of Civil Engineers, 1990)
      Laboratory resonant‐column and torsional shear tests are performed to determine the dynamic response (i.e., shear modulus and damping) of sands reinforced with discrete, randomly distributed fibers. The effect of fiber ...

    • Variability in Compaction Control 

      Iraj Noorany (American Society of Civil Engineers, 1990)
      A field study was made for evaluation of variability in degree of compaction of structural fills. Multiple runs of field‐density tests were performed at three sites by nine geotechnical engineering firms in San Diego, ...

    • Analysis of Laterally Loaded Piles Embedded in Layered Frozen Soil 

      G. Scott Crowther (American Society of Civil Engineers, 1990)
      A design approach is presented to analyze laterally loaded piles embedded in layered frozen soil. The design approach makes use of a commercially available computer solution that uses p‐y curves to model soil and pile ...

    • Deformation‐Based Model for Reinforced Sand 

      Scott E. Shewbridge; Nicholas Sitar (American Society of Civil Engineers, 1990)
      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 ...

    • Climate‐Controlled Soil Design Parameters for Mat Foundations 

      R. Gordon McKeen; Lawrence D. Johnson (American Society of Civil Engineers, 1990)
      Mat foundation design requires an analysis of the mat when subjected to unsupported regions due to swelling or shrinkage of expansive soils. A study was conducted to investigate simple rational methods for calculating the ...

    • Postdensification Penetration Resistance of Clean Sands 

      G. Mesri; T. W. Feng; J. M. Benak (American Society of Civil Engineers, 1990)
      Freshly consolidated or densified clean sands exhibit a substantial increase in stiffness under drained aging conditions. Laboratory measurements of dynamic shear modulus after primary consolidation and field measurements ...

    • Transport of Low‐Concentration Contaminants in Saturated Earthen Barriers 

      Yalcin B. Acar; Laique Haider (American Society of Civil Engineers, 1990)
