Improving Properties of Active Clay by Sand Admixtures
Characteristics of an active clay under various contents of sand are presented. The sand is an admixture used for improving properties of the active clay deposited at a marginal site....
Concrete Removal Techniques with Potential for Use in Rock
This paper describes concrete removal techniques that were employed in the rehabilitation of US Army Corps of Engineers mass concrete structures and are thought to have potential for limited...
Rock Excavations in Downtown Toronto
The geology of Toronto area is somewhat complex due to the series of advances and retreats of the glaciers. The overburden deposits consist of materials laid down during the Wisconsinan...
Numerical Modeling of Interface Behavior for Drilled Shaft Foundations Under Generalized Loading
To evaluate soil-foundation interaction numerically, an isoparametric thin layer element is used within a 3-D, material nonlinear, general purpose geotechnical analysis system developed...
Investigation and Modeling of Soil-Structure Interface Properties
An investigation of some techniques suggested to reduce friction at the soil-structure interface, for example plastic sheet on sand, is presented, and a model proposed for characterizing...
Fact or Friction: A Review of Soil Response to a Laterally Moving Pile
A review of soil response around a laterally moving pile is presented and 'Winkler' spring soil modulus variations are discussed. Based on available theory, and...
Ultimate Capacity of Deep Foundation by a Rigid-Plastic Analysis
This paper is concerned with the determination of the axial ultimate capacity of a rigid pier on the basis of the theory of perfect plasticity. As an application of the upper bound theorem...
Numerical Analysis of Vertically Loaded Pile Groups
An approach is presented for the analysis of linear and nonlinear response of vertically loaded pile groups. The piles are modeled with finite elements, the pile-soil influence through...
NEWNEG: Microcomputer Program for Downdrag on Piles
A microcomputer program called NEWNEG is presented. It addresses the problem of single piles subjected to downdrag. The analytical background relies on the equilibrium of the pile and...
Uncertainties in Offshore Axial Pile Capacity
The overall bias and error associated with the API recommended procedures and other popular methods for offshore pile design are evaluated. The paper considers single axial friction piles...
Risk Correction Factors for Bearing Capacity Analysis
In this paper bearing capacity correction factors are developed to account for the randomness in the load and soil properties. These are applied to the bearing capacity equation in the...
Comparative Performance of Two Pile Types
This paper reports on the pile driving and load bearing characteristics of the two pile types driven at a plant site in Sumatra, Indonesia. Nine prestressed concrete piles were driven...
Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...
Augered Cast-in-Place Piles
Development of the augered cast-in-place pile system from origination in the late 1940's to the present state of the art is presented, with methods of pile placement, including...
Contribution of Soil Freeze to Pile Capacity
In order to investigate the magnitude and rate of increase in load capacity for piles installed in clayey soils, a series of load tests were performed at various intervals of time following...
Bearing Capacity of Shallow Strip Foundation on Strong Clay Underlain by Weak Clay
Laboratory model test results for the ultimate bearing capacity of shallow strip foundations supported by a stiff clay layer underlain by a weaker clay layer have been presented. The model...
Effect of Void on Footing Behavior Under Eccentric and Inclined Loads
The effect of underground void on the behavior of strip footings subjected to eccentric and inclined loads was investigated using the finite element method of analysis. Results of the...
Performance of a Large Ribbed Mat on Cohesive Soil
The performance of a 678-ft by 304-ft (207-m by 93-m) ribbed concrete mat was studied to provide improved soil input parameters for design. The mat was constructed on a low plasticity...
Bearing Capacity of Shallow Foundation on Granular Column in Weak Clay
Laboratory model tests results for the ultimate bearing capacity of shallow rectangular foundations supported by granular columns made in weak clay have been presented. In all cases, the...
Field Performance of a Soil Nail System in Loess
This paper presents data from measurements of a soil nail system constructed in loess soil in Pullman, Washington. The soil nail system is designed to retain a 39.2 ft (11.9 m) high excavation...
