RCC Mixes and Properties Using Poor Quality Materials?Concepcion Dam
This paper discusses aggregate studies, mix investigations, and material property tests for the relatively poor quality materials available for use in RCC at Concepcion Dam....

Thermal-Structural Analysis Methods for RCC Dams
Current procedures for evaluating temperature control and the placement of contraction joints in roller compacted concrete dams are not always evaluated with the aid of detailed analysis...

Beach Nourishment with Aragonite and Tuned Structures
The first full-scale use in the United States of imported aragonite sand for beach restoration was undertaken at Fisher Island, Florida, between December 1990 and April 1991. About 20,000...

Monitoring of the 1988 Boca Raton Beach Nourishment Project
During July and August of 1988, approximately 843,000 cm of sand was placed along a 2.3-km stretch of beach in Boca Raton, Florida. Post-cosntruction monitoring of the beach nourishment...

Mitigation of Harbor Caused Shore Erosion with Beach Nourishment Delayed Mitigation, St. Joseph Harbor, MI
St. Joseph Harbor MI. was the first Corps of Engineers Section 111 erosion-mitigation project to be built. Between 1 Jun 76 and 5 Aug 85, about 1,067,000 cy of fine sand was placed in...

Design of Protective Dunes at Dam Neck, Virginia
Dunes act as a primary coastal defense against inundation in the Netherlands and the Dutch Government has devoted considerable effort towards development of reliable procedures for the...

Subaqueous Disposal Area Development and Mitigation
Development of subaqueous dikes on soft soils extensively utilized geosynthetics. The design adopted a wide-bermed embankment with high-strength geotextile for tensile reinforcement and...

Concrete for Sealing Voids in Rubble Structures
Permeability of rubble-mound breakwaters and jetties to sand transport and wave transmission results in increased costs for dredging and navigation. Guidance is provided for economically...

A Design Manual for Coastal Fluidization Systems
This paper summarizes a recently completed design manual on fluidization systems to manage sand in the coastal environment for sand bypassing at inlets and harbor mouths and for creating...

Simulated Field Trials of Non-Destructive Concrete Test Methods for Highway Structures
The data presented results from a two year Strategic Highway Research Program investigation into suitable NDT methods for determining the early age, and residual strengths of highway structures....

Dynamic Compaction of Nuclear Waste
When ponding, caused by settlement of the original soil cover over low-level nuclear waste buried at the Department of Energy's Savannah River Nuclear Plant near Aiken, S.C.,...

Cleaning Up Chromium
From 1956 to 1985, the United Chrome Products plant in Corvallis, Oregon, took a steady toll on the environment. Leaky plating tanks and the discharge of rinse water into a disposal pit...

Grouting, Soil Improvement and Geosynthetics
The proceedings of the 1992 ASCE Specialty Conference on Grouting, Soil Improvement and Geosynthetics, addresses advances in the state-of-practice, research and technological developments...

Automating The Corps
Automated soil testing machines solved several problems at once for the U.S. Army Corps of Engineers' South Western Division Laboratory in Dallas, Texas. The machines replaced...

Geomechanics of Subsidence Due to Pumping of Groundwater
In this talk we describe a nonlinear theory for the classical problem of pumping of groundwater from a layered soil. The model soil system consists of three horizontal layers where a very...

Micromechanics and Effective Properties of Elastic Particulate Composites
A new micromechanical framework is proposed to investigate the effective mechanical properties of elastic particulate multiphase composites. Exact ensemble-volume averaged field equations...

Quantitative Stereology of Concrete Microcracking
Stereological methods enable extrapolation of quantitative microcrack characterization from two dimensions to three dimensional space. However, because these quantifying techniques are...

Experimental Determination of the Relation Between the Damaged Zone and the Aggregate Size in Concrete Through Acoustic and Mechanical Techniques
The size of aggregates in concrete has an influence on the behavior of the material. The width of the localized band can be related to this characteristic. Different experimental techniques...

Mechanical Characterization of the Soft Tissue in Horse Hooves
The laminar corium tissue of the equine distal digit (or horse hoof) has been tested uniaxial tension. The laminar corium tissue lies between the hoof wall and the underlying bone of the...

Random Aspect of the Stress Inside Granular Media
Micromechanics of granular media arose from the necessity of a better understanding of the relationship between the global behaviour of such materials and the physical phenomena which...
