Soil-Cement Mixed Wall Technique
This paper introduces the soil-cement mixed wall technique and its applications for the installation of cutoff walls, excavation support walls and soil-crete columns for soil stabilization....

Stabilization of Collapsible Alluvial Soil Using Dynamic Compaction
The effectiveness of dynamic compaction for improving collapsible soils was evaluated under field conditions using full scale load tests performed on 1.5 m square footings. Tests were...

Three-Dimensional Nonlinear Study of Piles and Simplified Models
In a recent study the authors examined the effect of the nonlinear behavior of soil on the axial and lateral response of one or two piles due to monotonic and cyclic pseudodynamic loading...

Monte Carlo Simulations of the Dynamic Response of Pile Groups
A study is presented on the effect of variations of relevant parameters within a pile group on the vertical dynamic response of the group. These parameters include the shear wave velocity...

Evaluation of Geotechnical Design Parameters by Expert System Techniques
This study refers to application of an artificial intelligence technique to evaluate geotechnical design parameters in the soil design definition. This complex evaluation is incorporeted...

Do Simplistic Methods of Foundation Design Produce Reliable Foundations?
Many foundations today are designed using deterministic (single value) analysis techniques which do not reflect the natural variability of soil properties. If the standard deviation and...

Dynamic Testing to Predict Static Performance of Drilled Shafts Results of FHWA Research
The paper describes the preliminary results of recent research sponsored by the FHWA on predicting by relatively economical dynamic methods, the static capacity and performance of drilled...

Reliability in Rock Engineering
This paper reviews approaches to reliability in rock engineering through a survey of methods developed at MIT. Since these methods are intended to be applied in engineering decisions,...

Data Base of Seismic Body Wave Velocities and Geotechnical Properties
A data base of seismic velocities measured in soils and standard geotechnical engineering material properties has been established at the U.S. Army Engineer Waterways Experiment Station...

Earthquake Measures for California OCS Platforms
The ability of a platform to withstand earthquakes is one of the primary design factors for platforms on the California outer continental shelf (OCS). This paper discusses (1) the special...

Model Comparisons of Harbor Wave Response
Physical and numerical model tests were conducted for an idealized, flat-bottom rectangular harbor, entrance channel, and nearshore bathymetry. Bathymetry of the entrance channel and offshore...

Experiments on Stratified Flows: A Comparison with Theory
Stratified flows caused by salt wedges in estuaries, fjord flows and power station cooling waters represent very complicated flow situations with regard to their stability and rates of...

Results from Selected Oil-Spill Response Research
Recent large oil spills from tankers have reaffirmed the need for continuing technology assessment and research to improve oil-spill response capabilities. The Minerals Management Service...

Scour Around Cylindrical Piles Due to Wave Motion in the Surf-Zone
The paper discusses the results of experimental tests to study scouring phenomena around cylindrical piles during a sea storm with reference to the modelling of a beach profile in the...

Management of Great Lakes' Sandy Barriers: The Conceptual Challenges
Sandy barriers are dynamic, significant, and sensitive resource systems, comprising portions of the 18,000 km of Great Lakes shore. Use, development, and management of these features,...

Moving Muds in the Marine Environment
Fine sediments with cohesive properties abound in the marine environment. We review idealized relationships that are useful in understanding flow behavior of important components of marine...

Functioning of Multi-Row Sand Fences in Forming Foredunes
Foredunes on sandy beaches are best developed through use of a series of fences by which dune height and width can be controlled. In a previous paper, the authors examined the functioning...

Turbulence Modelling of Suspended Sediment in the Surf Zone
A computational model is developed for the prediction of the wave period averaged turbulence structure under a breaking wave. The principal forcing function for the model is the generation...

Process Variation Across a Barred, Tidal Nearshore
Detailed measurements of nearshore motions and morphologic change across the inner bar-trough of a barred, tidal beach were taken at Canaveral N.S., Florida. Tidal range was <1...

The Sedimentary Organisation and Behaviour of Drift-Aligned Gravel Barriers
Drift-aligned barriers formed of coarse clastic materials and described in terms of their organisational evolution at two levels, a) sorting and selection of clasts; b) development of...
