Design and Monitoring of an Ice Drill Pad
An ice pad was sucessfully designed and built to provide a suitable foundation for an exploratory drill rig in the National Petroleum Reserve of Alaska in early 1985. Design considerations...
Ground Temperature Monitoring Cominco's Red Dog Project
Procedures are available in the literature for estimating subsurface thermal characteristics of foundation soils in cold regions using published climatic characteristics for a given area....
Characterization of the Dalton Highway Foundation Soils
A case study is presented of the landform-based probabilistic-statistical route geotechnical characterization of natural foundation soils along the Dalton Highway. Landforms were mapped...
Ice Cover Research?Present State and Future Needs
Presentation reviews, at first, a number of problem areas in ice engineering, such as the determination of vertical and horizontal forces floating ice covers exert on fixed structures,...
Finite Element Modelling of Cold Regions Concreting
Finite element heat transfer computer programs are discussed in regard to their use in modelling cold weather concreting. The concrete material properties required for input to the finite...
F.E.M. Analysis of Mobile Arctic Caisson Island With Stochastic Material Properties
The paper examines how soil uncertainty influences the short term settlements and stresses of the Mobile Arctic Caisson on the original sea bed. Utilizing a two-dimensional plane strain...
Moisture Effects on Extruded Polystyrene Insulation
The amount of moisture within the insulation was determined by carefully weighing each sample and then measuring its volume. Two methods of measuring thermal conductivity were used. The...
Insulation Performance Beneath Roads and Airfields in Alaska
Evaluations of the long-term thermal performance of installations in Alaska for frost heave control have included sampling and testing of the insulations to determine the retained thickness,...
Sheet Pile Interlock Behavior: A Moving Contract Problem
The finite element method is used to analyze the behavior of sheet pile interlocks subjected to an uniaxial pull test. The thumb and finger of the interlock provide three contact points...
Tunnel Closure Prediction by Finite Element Method
Discussed is the tunnel closure prediction of a drainage tunnel using finite element methods. Separately, three finite element programs were used to predict the closure. The results of...
A Laboratory Investigation of the Undrained Small Strain Behavior of London Clay
Three different total stress-paths were followed during shearing of the anisotropic consolidated (CAU) tests: compression, extension and a stress-path simulating an element under a plate...
Large Mat Foundation Analysis on Expansive Soil
This paper describes a comparison of predicted and observed performance of mat foundations on stiff expansive soil. Foundation performance was predicted using a new computer program BOSEF...
Landslide Damming in the Cordillera of Western Canada
Major landslide dams in the Cordillera are a result of rock slope movements, landslides in stratified Pleistocene deposits, and landslides in till or colluvium in steep mountain watersheds....
Expert Systems in an Engineering-Construction Firm
Although it has been generally accepted that the field of engineering provides a wide variety of potential applications for expert systems, most developments have been academic in nature....
Sequential Earthquake Response of an Earth Dam
Sequential earthquake-response records of the well-instrumented Long Valley earth dam (Mammoth Lake area in California) are analyzed and engineering interpretations are made. The dam,...
Pseudo-Dynamic Testing of Structural Components
The pseudo-dynamic testing procedure is a simultaneous simulation and control process in which inertia and damping properties are simulated and flexibility properties are acquired from...
Dynamic Tests of LNG Storage Tanks for Earthquake Analysis of Liquid-Tank-Pile-Soil Interaction
This paper presents a field test procedure for determining the dynamic properties of large liquid natural gas (LNG) storage tanks under operating conditions. Two methods of vibratory excitation...
Flexural Behavior of Reinforced Masonry Walls and Beams
Many reinforced masonry walls and beams were tested as a part of the U. S. -Japan cooperative research program on masonry building structures. Six concrete block and two clay brick masonry...
Stress-Strain Behavior of Grouted Hollow Unit Masonry
Experimental results from axial stress-strain tests including post-peak response on hollow unit masonry prisms are compared to those of previous researchers....
Soil-Structure Interaction on Structural Dynamics
The dynamic analysis of structures under the effect of soil-structure interaction and the effect of member axial force is based on the continuous mass matrix method, in which the equations...
