Pile Creep Designs for Frozen Layered Profiles
A concept of relative creep stiffness suitable for the evaluation of the long-term, uniform creep behavior of non-ice type, frozen soils is presented. This concept extends the current...
Creep Rate Analysis of Pile Load Test Data
The uniform creep behavior of five driven piles and one slurried pile based on pile load test data are presented and analyzed. The incremental static load tests carried out by ARCO, Alaska...
Research Challenges in Frozen Ground Pile Design
A fairly recent pile design analysis is reviewed. The influence of such factors as temperature, salinity, loading, etc. on frozen ground pile design is pointed out. Since many facets of...
Evaluation of Structures by Dynamic Load Testing
The Frequency Sweep Method for the evaluation of structures by dynamic load testing was developed by the senior author. It is a non-destructive testing (NDT) method that was originally...
Standards for Pile Load Tests in Permafrost
A requirement exists to establish standard procedures for conducting pile load tests in permanently frozen soils. The methods outlined in the ASTM Standards for piles in thawed soils do...
Attenuating Creep of Piles in Frozen Soils
Results of several long-term creep tests of piles in frozen soils are analyzed; the primary or attenuating creep is predominant in most cases. For effective design of pile foundations...
Snow Effects on Pile Design Temperatures
The construction of North Slope aboveground pipelines and gathering lines is generally from snow workpads constructed proximate to existing access roadways. The pile support centerline...
Geotechnical Behavior of Underreams in Pleistocene Clay
Enlarged bases are often constructed in cylindrical drilled-and-cast-in-situ foundation elements (footings, bored piles) to increase their capacity. Enlarged bases that are cut mechanically...
Review of Repeated Axial Load Tests on Deep Foundations
A review of the literature is presented on the axial capacity of deep foundations subjected to repeated loads. Data are summarized on anchors, driven piles, and drilled shafts. In general,...
Foundations in Permafrost and Seasonal Frost
The papers in this volume cover the following subject areas: A method that utilizes a decision matrix diagram for selecting the most suitable and economical foundations for construction...
Drilled Piers and Caissons II
Drilled piers or caissons, also called drilled shafts or bored piles, have long been a very cost effective foundation solution for many soil profile and load situations. A distinct advantage...
Unique Installation Methods for Large Interceptor in Poor Soil Conditions
The construction of approximately 1. 5 miles of a major sewer interceptor in downtown Boston encountered some unique construction challenges. The entire route required dewatering during...
Instrumentation for an Uplifting Ice Force Model
Pile-supported, light duty structures are especially vulnerable to the uplifting forces. To evaluate the parameters that control the magnitude of the uplifting force a laboratory model...
Design of Guideway Substructure Dada County METROMOVER
This paper describes the procedures and parameters used for the design of the guideway substructure for the Dade County METROMOVER system. The substructure for this work is defined to...
Summary Evaluation of Dade County's APM Foundations
This paper presents an overview of the engineering performance and cost effectiveness of the guideway and station foundations of Dade County's Automated People Mover (APM)....
Foundation Design Considerations for Detroit DPM
The design loadings for support of the elevated guideway of the Detroit Downtown People Mover (DPM) consist of high vertical as well as horizontal loads. In order to simplify foundation...
Tunneling Operations and Equipment
The papers included in the Proceedings describe four diverse tunneling prjects of varying diameters, design criteria, ground conditions and construction techniques undertaken at locations...
Coefficient of Variation of In Situ Tests in Sand
For a research project on the behavior of piles in sand for the United States Geological Survey and the Federal Highway Administration, ten sites were selected where detailed load tests...
LAX Takes Flight for the 1984 Olympics
LAX (the Los Angeles airport) had over two dozen contractors working on site to complete their $700 million improvement plan in time for the Olympics in July. They also came up with several...
Seismic Design for Highway Bridge Foundations
This paper focuses on the determination of stiffness characteristics of piles and pile groups. Both battered and vertical pile groups are considered. Recommended methods for determining...
