Introduction to Immersed Tube Tunneling Symposium
Today's Symposium on Immersed Tube Tunneling is a continuation of a series of papers that began at Construction Congress '89 with discussion of mined tunnel subaqueous...

Jointless Redecking
If you're redecking a bridge, why not eliminate a major cause of its corrosion at the same time? Why not remove the expansion joints? The Department of Public Works in Steuben...

Seismic Design and Performance of Railroad Bridges
Damage to railroad bridges during earthquakes in the United States and Japan is summarized. Research tasks are outlined to develop seismic design and retrofit criteria for railroad bridges....

Seismic Hazard Along a Crude Oil Pipeline in the Event of an 1811-1812 Type New Madrid Earthquake
This paper presents an assessment of the seismic hazard that exists along a major crude oil pipeline (pipeline 22). An 1811-1812 type New Madrid earthquake with moment magnitude 8.2 is...

Liquefaction Hazard Analysis for Design of the Kern River Pipeline at the Muddy River Crossing, Southern Nevada
The 91.4-cm (36-in.) diameter Kern River natural gas transmission pipeline will cross the Muddy River in Moapa Valley, about 5 km west of Glendale, Nevada, in an area of relatively low...

Two Approaches for Characterizing Images of Rail Surface Flaws
Rail surface flaws can be removed by grinding to improve the life of rail and provide a safe, smooth running surface. To avoid time consuming and costly visual inspection in the determination...

Computer Simulation and Disposition in Railway
The paper describes simulation package on high capacity personal computer. Sofware package PC-SIMU simulates extremely accurately the movement of trains within the region of the line suitable...

Experiments with Formal Specifications on MAGGALY
Until lately, safety functions for automatic train driving systems have mostly been implemented with classical techniques such as relays, way circuitry and, more recently, electronic devices....

Safety Microprocessors in Guided Ground Transport
The use of microprocessors performing safety tasks such as Automatic Train Protection systems made more difficult their safety-worthiness assesment. In this paper we will first examine...

Riverbank Renewal
In Providence, project teams from the public and private sector worked side-by-side, rerouting two rivers and constructing a new corporate headquarters. What made the task more challenging...

Pipeline Field Experiment at Parkfield, CA
A field experiment designed to investigate the performance of buried pipelines at a fault crossing has been constructed near Parkfield, CA. The site was chosen to capitalize on the predicted...

Dynamic Load Computation for Flexible Guideways Under Moving Vehicles Within a Multibody Approach
This paper addresses the problem of the dynamic interaction of vehicles with their supporting guideway. Because of topographical and environmental reasons, modern railways and magnetically...

Fatigue Reliability and Remaining Fatigue Life of Existing Steel Rail-Road Bridges
This paper presents a fatigue reliability model for the reliability-based evaluation of remaining fatigue life of existing rail-road bridges. It is demonstrated that the simple fatigue...

Research on Structural System Reliability of Cable-Stayed P.C. Railway Bridge Across Hong-Shui River
This paper analyses the structural system reliability of cable-stayed bridge by using the modified all failure modes. The concept of the structural subsystem is used to help the selection...

A Supertrain Solution?
A high speed steel wheel rail line has been highly successful in France, where ridership has been very high. Financial backers were paid back in seven years, half the projected payback...

Next Stop: The Los Angeles Metro Rail
The Los Angeles Metro Rail is a $6.5 billion light and heavy rail system, which may be entirely completed by the year 2000. A 22 mi segment of the 150 mi light rail system, connecting...

Whitfield Reservoir Inlet Outlet Pipeline
Alameda County Water District reports on the planning, design and construction of a 48-inch water main installed under modern urban circumstances. The location of the pipe and the construction...

Twin Pipeline Crossing of the Fraser River
A new creek water supply was developed for the communities of Mission and Matsqui, British Columbia, Canada, in the early eighties. Over 60 kilometres of 450 mm to 900 mm diameter ductile...

CTA's Experience in Fostering Station Redevelopment Through Public/Private Partnerships
The paper reviews the experience of the Chicago Transit Authority's partnerships with the private sector. The funding, space, design, construction and operation components...

The Magnetically Levitated Transport System TRANSRAPID?Characteristics and Aspects of Application
After a development of less than two decades the magnetic levitation TRANSRAPID is virtually ready for revenue service since 1985. The service has been continuously tested since 1985 on...
