Grouting a Sand Dam
Hardy Dam, owned by Michigan's Consumers Power Co., was constructed in 1929 by dumping sand from railroad trestles for an embankment to support a concrete core wall. Some...
Spreadsheets: A New Design Tool
New techniques are developing which make computer programming easier. One new technique is spreadsheet programming for microcomputers. Two programs are presented which give a quick overall...
Saving the Lady
Restoration of the Statue of Liberty is as much an exercise in cooperative management as it is in technical design and execution. Among those sharing management responsibility are: the...
Concrete Rehabilitation Options and Solutions
This paper demonstrates the basic steps for a successful rehabilitation program using a case study of the rehabilitation work for the NASA/JPL 64-meter deep space communication antenna....
Tunnel and Bridge Construction with Minimum Disturbance to Overhead Services
The rapid growth of pipe jacking over the last 20 years and the improvement and development of methods in terms of lengths of drive, size and ability to work in varying ground conditions...
Design of Strontia Springs Arch Dam
The development of the layout and the history of design of the 292 foot (89 m) high Strontia Springs Dam is presented. While a brief description of the general project layout and foundation...
Geology of the Strontia Springs Arch Dam
Precambrian metamorphic gneisses comprised the foundation rock at Strontia Springs Damsite. Geologic exploration at the axis selected for the arch dam revealed a large shear zone which...
Geotechnical Aspects of Strontia Springs Arch Dam
The bedrock at the Strontia Springs damsite consists of generally excellent quality granitic and metamorphic rock, except for a wide shear zone located beneath the dam in the lower valley...
Hydraulic Design of the Strontia Springs Diversion Dam
The hydraulic features which were of primary significance for the project were the diversion tunnel and spillway. The low-level outlet valves and water-supply intake were relatively straight-forward...
Construction of Strontia Springs Dam
Strontia Springs Dam is a principal feature of the Foothills Project on the South Platte River, 25 miles southwest of Denver, Colorado. The dam provides for storage and diversion of water...
Concrete Quality Control and Quality Assurance on Strontia Springs Dam
An essential part of the construction management services provided on Strontia Springs Dam was the quality control of material, mixture proportions, and production for all concrete placed...
Overview of Artificial Island Design and Construction in the Arctic
An overview is provided of the design and construction of artificial islands in the Arctic. Since the early seventies more than 20 islands have been constructed in the Alaskan and Canadian...
Arctic Island Construction
The history of island building in the Beaufort Sea of Canada and the United States is reviewed. Construction methods are discussed. These include hauling material from onshore in both...
Arctic Offshore Site Investigations
The continuing search for new petroleum sources has led to increased exploration activity in the arctic offshore regions of Alaska. The general approach to site investigations has been...
Probabilistic Design of Gravity Foundations for Arctic Offshore Structures
The use of the probabilistic simulation technique to estimate the variability of the resistance and the ice load on arctic gravity structures is illustrated in order to assess the safety...
Creep Properties of Ice: Theory and Experiment
In recent years, intensive developments in Northern regions have increased the demand for solutions to a large number of engineering problems involving ice mechanics. In particular, these...
Soil-Pipeline Interaction During Ground Movement
The problem of the elastic interaction is examined between a pipeline or a group of connected flexible connected pipelines and the surrounding soil medium, which is induced by ground movement....
Structural Solutions for the Enhancement of Gravity Foundations on Very Soft Arctic Soils
Very soft soils in several offshore Arctic areas cause a major concern in the design of gravity foundations, particularly in view of the high magnitudes of ice loads. Preliminary studies...
Stochastic Finite Element Analysis of Gravity Platform Foundation
Gravity foundation design requires determination of total and differential settlement, vertical stress distribution beneath the raft and maximum shear stresses in the sand layers in the...
Thaw Settlement as a Result of Permafrost Deterioration
An overview is given of floor and footing failure as a result of deterioration of permafrost. Consideration of causes for the deterioration and methods of repair are addressed in general...
