Compaction Grouting as an Aid to Construction
The traditional use of compaction grouting has been to arrest settlement of existing structures, and occasionally to raise them back to their original grades. Recently, the process has...
Ground Modification for a 14-Story Structure Over a Deep Peat Deposit
The foundation design and construction for a 14-story reinforced concrete office building northwest of Minneapolis is described. The building's geometry provided unusual foundation...
Static Behavior of Piles in Cemented Calcareous Sands
A series of instrumented jacked model pile tests and another series of uninstrumented grouted model pile tests in a cemented calcareous sand were performed. The influence of pile installation...
Tangent Modulus of Piles Determined from Strain Data
When evaluating measurements of strain or telltale shortening of a pile subjected to loading test, precise knowledge of the 'elastic' modulus is necessary. By means of plotting and analyzing...
Modelling of Displacement Piles in Sand Using a Pressure Chamber
This paper describes a method of modelling the driving and loading of piles in the laboratory that permits variations of significant parameters and maintains effective stresses at levels...
On the Critical Relative Displacement of Pile Shaft and Surrounding Soil
Model pile pull-out tests have been conducted to investigate the characteristics of the critical relative displacement at which the critical pile skin resistance is mobilized. Test results...
The Influence of Cyclic Loading on the Lateral Load Response of Groups of Piles
The effects of cyclic loading on the lateral response of closely spaced groups of piles has been widely considered to be a single pile phenomenon, related to gapping and scour around the...
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...
Settlement of Single Piles
This paper presents an application of a recently developed approach for computing the tip settlement of axially loaded single piles driven into compressible layered soil system. In this...
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...
Ground Failure Damage to Buildings During Earthquakes
Several case histories are examined to evaluate building damage as a function of the foundation type and type and amount of ground displacement. Extensional or vertical ground displacements...
Simplified Seismic Analysis of Pile Foundations
The determination of displacement of the pile cap and displacements and forces of individual piles is essential to the design of pile foundation subject to both static and/or dynamic loading....
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...
Structural Foundation Practices for Highway Projects
The state-of-practice by State transportation agencies, in the area of structural foundations, is compared between the late 1970's and the present. The structural foundation...
Analysis of Pile Load Tests at Lock and Dam 26
This is a summary of the results collected during the extensive load test program performed by the U.S. Army Engineer District, St. Louis, during the construction of the new Lock and Dam...
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...
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...
