Geotechnical Database Management Systems for Boston's Central Artery/Harbor Tunnel Project
This paper presents a geotechnical computer application currently in use on Boston's Central Artery/Harbor Tunnel (CA/T) Project. The application is designed to manage subsurface...

Recent Developments in Hardware and Data Processing for Telemonitoring Various Structures
Some of the latest automated centralized monitoring systems being used by civil engineers in France shall be reviewed, along with details of the benefits from this approach and some of...

Determination of the Deformation Characteristics of a Jet-Grouted Shallow Tunnel in Alluvial Deposits by Means of In-Situ Measurements and Back Analysis
The deformation characteristics of a jet-grouted shallow tunnel in alluvial deposits are investigated. An intensive in-situ measuring program accompanied each of the various excavation...

Pressuremeter Stress Relaxation Testing in a Permafrost Tunnel
In the spring of 1988, a geotechnical testing program was carried out in the U.S. Army CRREL Permafrost Tunnel, located at Fox, near Fairbanks, Alaska. In all, some thirty cone penetrometer...

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...

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,...

Finite Element Analysis and Field Instrumentation of a Soil/Cement Arch
A two dimensional plane strain finite element analysis is used to predict the increase in stress on an existing tunnel caused by the addition of twelve feet of fill. The fill, soil/cement,...

Performance of Building Resistance to Water, Waves and Erosion
Water damage to buildings due to Hugo was widespread and severe throughout low-lying coastal areas. Flood insurance claim payments have already exceeded $350 million, the largest payout...

Hurricane Hugo vs Critical Lifelines
Hurricane Hugo significantly affected the performance of critical lifelines in South and North Carolina. An overview of the performance of power supply, transportation, communication,...

Hurricane Hugo's Effect on Marina Structures
The author has visited over twenty-five sites along the South Carolina coast and in Puerto Rico to ascertain the effects of Hurricane Hugo on marina facilities. Types of structures evaluated...

Effects of Hurricane Hugo On Water and Wastewater Systems of the Charleston Commissioners of Public Works
Hurricane Hugo had a major impact on the operations of the Charleston Commissioners of Public Works in their effort to provide safe water and wastewater service to their customers. Through...

Lessons Learned by the News Media
The paper summarizes a few things learned from the news media's experience in Hurricane Hugo and which they will try to do differently the next time. These include: simulcasting...

CZMA Consistency Opinions: An Undiscovered Body of Law
The Coastal Zone Management Act allows states to block the issuance of Federal licenses and permits if the permitted activity would be inconsistent with the state's Federally...

Citizen Participation in Regional Planning Efforts
During the past 4 decades the formal role of citizens has become increasingly more apparent under changing legislative mandates. This paper examines citizen participation in developing...

The Dispersion of Ocean Outfall Plumes: Physical and Biological Dynamics
The discharge of municipal wastewater into the coastal ocean through large ocean outfalls is an important component in managing sewage wastes generated by heavily populated urban areas...

Moored Systems for Time Series Observations of Bio-optical and Physical Variability in the Coastal Ocean
Recently, multivariable moored systems (MVMS) have been developed to study the ecology and physics of the upper ocean. Concurrent MVMS measurements provide time series of beam attenuation...

Measurements of Nutrient and Metal Fluxes from the Sea Floor in the Area Around the Whites Point Sewage Outfall, Los Angeles, California
Studies are underway to determine the influence of sewage outfall-impacted sediment on the exchange of nutrients and trace metals in the coastal marine environment. Utilizing a benthic...

Regional Monitoring in Southern California
Increasing concern about larger-scale, longer-term, and cumulative environmental effects has outstripped the ability of traditional point-source monitoring programs to provide useful information....

Mixing and Dispersion Processes in the Vicinity of an Ocean Outfall System in Southern California
Ocean wastewater plumes are important for the disposal of municipal wastes in Southern California. These plumes, which are discharged from sanitation systems, can be distinguished in the...

Offshore Oil Terminals?Potential Role in U.S. Petroleum Distribution
The construction of port facilities in deep water, several miles seaward from the nations's coastline, is one of the measures that have been suggested for reducing oil tanker...
