Project Layout
Microtunneling projects should be laid out with attention to the benefits and constraints unique to this construction process. The following recommendations address some of these concerns:...
Shaft Considerations
Jacking and receiving shaft locations should be selected to minimize the number of shafts and disruptions while not exceeding the practical limits of the drive lengths achievable for a...
Shafts/Temporary Structures
Shafts should be of a size to accommodate the equipment and pipe selected and to allow for safe working practices. If the shaft must accommodate the permanent works, it is the contractor's...
Size and Scale Effects on the Shear Strength of Concrete Beams
This paper identifies and discusses the role of proper geometric scale of relevant parameters in the size effect in shear, particularly in terms of practical beam design. In the overall...
Non-Destructive Strength Evaluation of a Continuous, Reinforced Concrete Slab Bridge
In the state of New Mexico, a significant number of reinforced concrete slab (RCS) bridges provide service on interstate highways I-10, I-25, and I-40 that are subjected to large amounts...
Application of TOPNET in the Distributed Model Intercomparison Project (DMIP)
This paper describes the application of a networked version of TOPMODEL, TOPNET, as part of the Distributed Model Intercomparison Project, DMIP. The model implementation is based on a...
San Diego Delivers
To maintain its ability to provide water to some of its rapidly growing regions, the city of San Diego is simultaneously laying two large diameter pipelines, one carrying potable water...
Nanotechnology Takes Roots
Nanoscale particles of zero-valent iron with a trace of noble metal catalyst are punching well above their weight in the area of environmental remediation. Their ability to destroy a wide...
Nonlocal Integral Formulations of Plasticity and Damage: Survey of Progress
Modeling of the evolution of distributed damage such as microcracking, void formation, and softening frictional slip necessitates strain-softening constitutive models. The nonlocal continuum...
Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...
Great Excavations
By any definition, the scale of the underground caverns being excavated near Geneva at the particle physics center run by the Conseil Europ�en pour la Recherche Nucl�aire (CERN)�the European...
Design Live Loads for Parking Garages
The objective of this research project is to obtain a better understanding of parking garage live loads and to recommend an appropriate value for design. A load survey was conducted in...
Microtunneling under Honolulu
Highly congested urban utility corridors present some of the most difficult conditions for construction of new underground pipelines, especially when subsurface conditions are also very...
Order Amid Uncertainty (Available in Geoenvironmental special issue only)
Bayesian statistical methods allow engineers to deduce probabilities from incomplete information. If there is a theoretical or empirical reason why a particular probability distribution...
Basin Response Time: Potential Hydrologic Basin Handprint
Hydrologic lead time is an important factor in many water resources engineering applications. The determination of the response time of a watershed to runoff-producing rainfall is the...
Comparison of Complete Modeling/Simplified Modeling of Zaragoza City Water Supply Network
(No paper) Zaragoza is a Spanish city with 600.000 inhabitants and a water supply network of 900km long. The Council technical services uses a Microstation based GIS, GRED, for network...
Securing the Stone
To prevent spalling at edges on thin stone veneer, engineers who design stone cladding pay special attention to the connection details. Kerf clips, 100-150 mm long, that distribute load...
Imaging Technologies

This proceedings includes the papers submitted to the Second International Conference on Imaging Technologies: Techniques and Applications in Civil Engineering sponsored by the Engineering...
Mechanics of Deformation and Flow of Particulate Materials
This proceedings is composed of written contributions to the nine-session symposium on the Mechanics of Particulate Materials at the McNU Conference held at Evanston, Illinois, June 29-July...
Factories for the Information Age
As the demand for computer chips continues to soar, designers of microelectronics manufacturing facilities must keep pace with exacting building requirements. Successful projects require...
