Soil Cement Shore Protection in Arctic Environment
Suitability of compacted and plastic soil cement prepared with sea water, for shore protection of islands in Arctic marine environment, is investigated. The laboratory test results indicate...
Ice Floe Impact Force on Vertical Sided Structures
A solution is described that does not assume a contact pressure-area curve or ice crushing strength. The impact force is related to Korzhavin's ice crushing equation by simple...
The Calculation of Ice Forces on Arctic Structures
Results of tests conducted to determine the relationship between uniaxial compressive strength of ice and crushing force are presented. A plot of normalized uniaxial compressive strength...
Triaxial Compression Testing of Ice
An understanding of the confined compressive strength of ice is needed to develop constitutive equations and failure criteria for analytical ice-structure interaction models. Procedures...
Centrifugal Modeling of Ice Forces on Single Piles
The ice forces and ice floe failure mechanisms associated with an ice sheet surrounding a vertical cylindrical pile were evaluated. A test system was developed to model ice forces in gravity...
Strength and Deformation Behavior of Frozen Saline Sand and Gravel
Construction of offshore oil and gas exploration and production structures often considers the use of either sand or gravel fill materials. Fill soils exposed to the environment will progressively...
Spalling and Buckling of Ice Sheets
The effect of local eccentricity in the vertical direction on the magnitude of compressive strength of wide ice sheets is studied theoretically. Two new failure modes are identified: indentation...
Relationships between Shear Wave Velocity and Depth of Overburden
Relationships between in-situ shear wave velocity and depth of overburden have been derived for various Quaternary age soils encountered primarily in Southern California. The geotechnical...
Creep of a Strip Footing on Ice-Rich Permafrost
Creep settlement tests were performed on a strip footing founded on the surface of ice-rich aeolian silt permafrost. The tests consisted of applying four step loadings to a 10 in. (25....
A Space Age Test Center
The Air Force's Aeropropulsion System Test Facility (ASTF) is the most expensive project the Air Force has ever built. Its massive heaters, coolers and compressors will treat...
Torsional Simple Shear Apparatus for Drained and Undrained Cyclic Testing
Since a cyclic triaxial compression apparatus was first used to study liquefaction of saturated sandy soil, many different types of cyclic shear devices have been used to investigate drained...
Rockfill Compression Tests and Other Aspects of the Design of Miel I Dam
The Miel I Dam, a high concrete face rockfill dam, is one of the main structures designed for the Miel I Hydroelectric Project in Colombia. Selection of dam type was based on technical...
State of the Art in Concrete-Polymer Materials
Concrete-polymer materials represent a relatively new technology in the construction industry. In some cases polymers are combined with portland cement concrete and, in other cases, polymers...
Concrete Face Rockfill Dams?Design, Construction, and Performance
Concrete face rockfill dams are being used with greater frequency and to greater heights in the last decade. The developments leading to this progress are many and are addressed in the...
Compression Load Tests on Concrete Piles in Alluvium
A series of tests was accomplished during the design phase for the West Seattle Freeway Bridge Replacement project. The results of instrumented compression load tests in alluvial deposits...
Study on Secondary Compression of Clays
An elastoviscoplastic constitutive model shows that a strain rate effect parameter is related to the coefficient of secondary compression. The relation was verified experimentally by test...
Consolidation-Strength Analysis for Soft Soils
A one-dimensional consolidation analysis including prediction of consequent shear strength increase for soft soils which exhibit large secondary compression is proposed. Consolidation...
Dredge Spoil Disposal Predictions and Performance: A Case History
A 146-acre dredge spoil disposal facility was constructed in Baltimore Harbor that received 3. 4 million cubic yards (2. 6 million cubic meters) of dredge spoil generated from construction...
Prediction of Peat Settlement
Compression of peat and organic clay deposits is characterized using a simple rheological model in which structural viscosity is assumed to be linear. The model utilizes three empirical...
Time and Stress Dependent Compression in Soft Sediments
Results are presented for laboratory experiments using a typical estuarine mud settling from a slurry in columns of 100mm diameter. Measurements have been made of density and pore water...
