Some Applications of Neural Networks in Structural Engineering
After a brief discussion of neural networks and their potential engineering applications, the author's on-going research in application of neural networks in structural engineering will...
Numerical Simulations of the CCS under the Joint Effects of Coastal Geometry and Surface Forcing
Using the S-Coordinate Rutgers University Model (SCRUM) of Song and Haidvogel(1993), a coupled coastal (86 m depth) and deep ocean (4600 m depth) California Coastal region has been investigated...
Boston's Backup Water Supply
For fifty years, Boston's sole real source of water has been the Hultman Aqueduct, but now final design is almost complete on the MetroWest Supply Tunnel, a new, larger conduit...
Low-frequency Fluctuations of Suspended Sand and Wave Groups in the Surf Zone
Field observations of the sand suspension near the bottom in surf zone are presented and discussed. Calculated spectra of suspended sand concentration and wave envelope was found to be...
Optical Remote Sensing of Wave Surface Kinematics
The measurement of the directional properties of surface slopes, velocities and accelerations is difficult, even in the laboratory, under conditions of steep, random and short-crested...
Modified Asphalt Binders - How Do They Compare?
This report summarizes some of the research that the US Army Engineer Waterways Experiment Station (WES) has conducted on asphalt modification of airport/airfield pavements. these laboratory...
Evaluation of the Pagosa Springs Geothermal Reservoir and Implications of Potential Additional Reservoir Development
The Town of Pagosa Springs is located 280 miles from Denver on the north bank of the San Juan River in southwest Colorado as shown on the Index Map, Some time before 1920 the first well...
Description of the Application of Goal Programming for Selective Withdrawal Structure Operation
Thermal stratification in reservoirs results in variations of water quality with depth. Selective withdrawal structures with outlets at different vertical locations, can be used to provide...
A Survey of Stormwater Infiltration Basins in the Puget Sound Region
A survey of 23 infiltration basins in the Puget Sound area was conducted to gain information on the performance of these systems and the degree of compliance with state agency guidelines....
Design of Clay Liner Permeability at Laboratory Scale Using Expert Systems
Unlike other soil properties, permeability of compacted clay is highly variable. The large number of parameters that affect permeability of compacted clay renders permeability unpredictable...
Quality Management of Earthwork Using Knowledge-based Systems
Earthwork is an integral part of many construction projects. It involves cleaning of the site, loading and spreading of soil, and soil compaction and leveling. Heterogeneous orientation...
Numerical Modeling of Initial Ground Movement in an Instrumented Superconducting Super Collider Shaft
A 5.5 m diameter shaft was sunk into a rock formation of Taylor Marl to a depth of 61 m at the Superconducting Super collider (SSC) site. Numerical modeling using finite difference analysis...
Vertical and Horizontal Deformations for Foundations on Sand: An Experimental Study
A natural scale model is used in order to investigate experimentally the sand soil deformation behavior which accepts loads by shallow foundations. The vertical and horizontal soil displacements...
Uplift Load-Displacement Behavior of Grillage Foundations
Full-scale field tests were conducted on steel grillage foundations for lattice transmission line towers that had been in place since 1929, 1947, and 1958. A total of eight tests were...
A Case History of Settlement of an Embankment on Lagoonal Deposits Influenced by Artesian Conditions
A geotechnical engineering investigation was performed for the Pearl Kai Center, a shopping center in the Pearl Harbor area of the island of Oahu, Hawaii. The proposed commercial development...
Towards a Rational Method of Predicting Settlements of Spread Footings on Sand
Prediction of settlements of both large and small spread footings on sand has traditionally been carried out using methods which are largely empirical. In recent years, advances have been...
An Alternative Formulation of Volume-change Behavior of Soils
The traditional approach based on the semi-logarithmic representation of volume change data is known to work relatively well for prediction of ground settlements. This approach has been...
Cyclic Loading for the Measuring of Soil Consolidation Parameters
A method of determination of soil consolidation characteristics using sinusoidal loading is described. It can be performed in laboratory test or in situ observation as well, with different...
Field Test of Thermal Precompression
A new concept for improvement of soft ground using moderate heating to control post-construction settlement is presented. The long-term creep behavior of a peat is presented based on laboratory...
Compressibility for Sand Under One-Dimensional Loading Condition
Empirical equations for one dimensional compression of sand do not include parameters characterizing properties of sand grains (e.g. moduli, size and shape of sand grains, and friction...
