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...
Movement Control of Excavation Support Systems by Iterative Design
Conventional design practice for excavation support systems emphasizes determination of loads and selection of structural components. This paper presents a method which uses movement control...
Some Expert System Applications in Geotechnical Engineering
Knowledge-based expert systems (KBES) represent a new technology for computer-aided engineering. These systems can be useful in situations which involve expert judgments for effective...
Geotechnical Judgment in Foundation Design
This paper summarizes the initial findings of a research project to investigate the judgment-making process of foundation engineers. Solutions for a typical design problem were solicited...
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...
Bearing Pressure?SPT Correlations for Expanded Base Piles in Sand
Design of enlarged base piles is usually carried out using correlations between SPT N values and point resistance. The results of full scale load tests are used to show that base resistance...
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...
New Design Method for Drilled Shafts from Common Soil and Rock Tests
A method is presented by which the compressive capacity and load-settlement characteristics of large drilled shafts can be computed from commonly executed soil and rock tests. The method...
Performance of High Capacity Caissons Founded on Decomposed Rock
The results of six load tests on large diameter caissons founded on decomposed rock are presented and analyzed. The caissons ranged from 1.5 m to 2.5 m in diameter and were 20 m to 23...
Caissons in Uplift in Sandy Soils
This paper describes the results of 10 full scale pullout tests conducted on short rigid caissons. Diameters ranged from 30 to 34 inches (760 to 860 mm) and lengths from 7 to 10 feet (2.1...
Interpretation of Load Tests on Drilled Shafts?Part 1: Axial Compression
Existing interpretation methods for axial compression load tests are reviewed critically, and a qualitative and quantitative comparison is made for selected methods. A simplified method,...
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...
Rectangular Footing on Nonhomogeneous Elastic Half Space
The problem of a rectangular footing or a strip footing on a nonhomogeneous elastic half space is studied in this paper. The medium is assumed to be isotropic with a variable shear modulus...
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...
Performance of Different Retention Systems in Similar Soils
Performance behaviour of three deep braced excavations in a similar soil profile, in the Chicago area is described. At each site, different bracing systems were utilized. Methods used...
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...
Statistical Analyses of Drilled Shaft and Embedded Pole Models
In recent years a significant effort has been made by the Electric Power Research Institute (EPRI) to develop new design models, to collect and summarize existing load test data and to...
