Assessment of Transmission Line Foundations
Electric utilities are faced with the need to build new transmission lines or to upgrade existing lines to meet future demands. Because of economic constraints and the difficulty of obtaining...
Structures for Enhanced Safety and Physical Security
This book presents the state-of-the-art in the general subject of structures for enhanced safety and physical security. The technical papers written are by engineers and researchers who...
Tension Leg Platform
a State of the Art Review
Prepared by the Task Group on Compliant Offshore Platforms of ASCE. This report considers the analysis and design of tension leg platforms (TLPs),...
Influence of Geologic Development on Horizontal Stress in Soil
Geologic history commonly controls the stress in natural soils, so that an understanding of the geology allows an assessment of the horizontal stress. This paper describes mechanistically...
Screw Plate Test for Drained and Undrained Soil Parameters
This paper describes a screw plate test device developed with a capability to measure the generation and dissipation of excess pore water pressure during testing in cohesive soils. The...
Cyclic Behavior of Natural Overconsolidated Clay in Two Loading Modes
One-way, stress-controlled, cyclic triaxial compression tests were conducted on a heavily overconsolidated (Ko > 1), slickensided, natural clay with a view to modeling its cyclic...
Characterization of a Site Underlain by Deep Collapsing Soils
The geomorphic setting of a site underlain by an 80 ft (24 m) deep deposit of collapsing silty sand is described. The field and laboratory investigation completed to characterize the geotechnical...
Helical Bearing Plate Foundations for Underpinning
Helical anchor foundations have been used in construction to provide resistance against uplift and compressive loading for structures such as transmission towers, tied walls, pipelines,...
Design and Construction of Stone Column Reinforced Cofferdams
A recent expansion of the North Carolina State Port Facility, at Wilmington, involved the use of six cellular cofferdams as earth retaining structures during dredging and final filling...
Power Pole Foundations in Reclaimed Mining Area
In central Florida, where strip mining for phosphate ore is a primary industry, street surfaces often become rolling because of differential settlement, and electrical transmission poles...
Jet Grouting to Construct a Soilcrete Wall Using a Twin Stem System
An existing coal loading pier located in Norfolk, Virginia was completed in 1961 for the purpose of loading ocean going ships. It was determined that dredging adjacent to the pier would...
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...
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...
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...
Subgrade Models for Soil-Structure Interaction Analysis
Historical development of improvements to Winkler's spring subgrade model are traced. The improvements consist of various ways to provide shear coupling between the springs....
Beams on Elastic Foundations: A New Approach
Using the Vlasov model, Vallabhan and Das have developed an effective iterative technique to solve the beam-on-elastic-foundation problem where the soil is assumed to have a uniform thickness...
A Geotechnical Analysis System with Applications for Drilled Shaft Foundations
The development and components of a geotechnical analysis system are described and illustrated for drilled shaft foundations. This finite element-based analysis system incorporates several...
