Design Methodology for Foundations on Stone Columns
Stone columns offer the geotechnical engineer a valuable and viable technique for stabilizing sites underlain by soils ranging from soft clays to loose silty sands. A discussion of the...
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....
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...
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...
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...
Transient Dynamic Response Analysis of Embedded Rigid Foundations
A simplified approach for the transient dynamic response analysis of embedded multiple rigid foundations is presented. The approach is based on approximate time-domain formulations of...
Subgrade Model for Static and Dynamic Response Analysis of Surface Foundations
A new subgrade model is presented for the static and dynamic response analysis of surface foundations. The model consists of a number of horizontal layer model units. Each model unit is...
Foundation Studied for Turbine-Generator on Liquefiable Soils
Turbine-generator foundations are generally constructed of concrete in the U.S.A. This paper deals with the dimensioning and evaluation of a turbine foundation in Oxnard, California. The...
Effect of Site Soil Properties on Seismic SSI Response of Embedded Structures
In a series of two-dimensional soil-structure interaction (SSI) analyses, seismic responses, including the SSI effect of a deeply embedded reactor building of a standard plant in different...
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...
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...
Geophysical and Nuclear Methods for Non-Destructive Evaluation of Caissons
Non-destructive testing techniques were used to confirm the concrete integrity on the caisson foundations for the 45-story Ohio Corporate Headquarters building in Cleveland, Ohio. 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...
Long Term Performance of High Rise Mat Foundation
The vertical movement of the foundation soils for a multi-story high rise office tower was monitored during foundation excavation, tower construction and the 25-year in-service period...
Response of Concrete Island Drilling System to Ice Impact Loading
The lateral stability and load/deformation characteristics of the Concrete Island Drilling System structure under ice impact loading conditions were studied. The 300-foot-square (91.5-meter...
Thoughts on the History and Current Practice of Foundation Engineering in North America
With the publication of 'Erdbaumechanik' in 1925, the behavior of soils was explained in terms of numerical physical properties and the principles of what became...
Reliability in Foundation Engineering Practice
The value and use of reliability concepts in foundation engineering practice are explored, with a focus on two complementary approaches. In the first, macroscopic and action-oriented,...
Sulfated Polysaccharides from Marine Invertebrates
The authors Laboratory is involved in the chemical and structural determination of sulfated polysaccharides from different sources. The main purpose of such studies is to compare these...
Countering Terrorist Threats
Musacchio & Rozen assessed the risks and vulnerabilities to a possible terrorist attack of the data processing center of a large European bank. With the increasing use by terrorist...
