Reinforced and Prestressed Concrete Pressure Pipe Diagnosis
Prestressed and reinforced concrete steel cylinder pipes are used for transmission mains, water intake lines, sewers force mains. Many collapses caused by the steel cylinder attack were...
Selection and use of Pipeline Leak Detection Methods for Liability Management into the 21st Century
Pipeline leak detection systems have been in use for many years on all types of pipelines with various products being transported. Pipeline owners and operators are subject to stringent...
Relocating a 54-Inch Diameter Force Main without Interrupting Wastewater Flow
The City of Tampa, Florida, was faced with the challenge of relocating three segments of an old 1372 mm (54-in.) diameter reinforced concrete pipe force main, totaling nearly a mile in...
Database for Pipeline Bridges in North America
Work began in 1985 at Wayne State University on a research study of pipeline suspension bridges. This effort, which was funded by ANR Pipeline Company of Detroit, Michigan, investigated...
The Load Factor
Spangler's load-factor formula for projecting conduits is generalized to all cases of buried rigid pipe, whether in trenches or under embankments; this is in accordance with the analytical...
Influence of Lateral Wind on Driving on Offshore Bridge
The Honshu-Shikoku Bridges are a system of highways crossing over the sea, where cross-winds variously affect vehicle behaviour. This is the intermediate report on the surveys aimed at...
Behavior of Suction Piles in Sand
In the marine environment, use of suction pressure for the installation of sealed top piles (suction piles) is a promising alternative to driven pile foundations, particularly in deep...
Transmitted Swelling Pressures on Retaining Structures
The main objectives of this paper are to describe a finite element model to simulate the lateral swelling behavior of expansive soils as a function of soil suction change in the soil domain...
Elasto-Plastic Volume Change of Unsaturated Compacted Clay
Isotropic compression tests were performed on samples of unsaturated compacted kaolin in a modified triaxial cell that allowed separate control of pore water pressure and pore air pressure....
One and Three Dimensional, Three Phase Deformation in Soil
An initially saturated soil exhibits two distinct deformation patterns as it drys. First, it deforms vertically until the soil begins to drain. Secondly , it deforms laterally as well...
Slip-Lining Solution
Grouting the annular space between a corroded sewer pipe and newly installed liner pipe is a stage of a typical sewer line rehabilitation project which contains hidden problems and difficulties....
As the Clock Winds Down
This chapter discusses the waning stages of negotiations....
The Assessment of Armourstone for Shoreline Protection
To protect shorelines from erosion, Ontario Hydro is using armourstone at various Generating Stations along the perimeter of the Great Lakes. Armourstone is carefully evaluated prior to...
Gravel Equilibrium Beach Design for Arresting Shore Erosion at Flathead Lake, Montana
Erosion of the north shore of Flathead Lake, Montana, is caused by summer wind waves generated along a 22-mile fetch. The preferred method for arresting erosion there is a beach composed...
Comparison of Model and Field Results for Barbers Point Harbor
As waves travel into harbors from deep water, nonlinear processes lead to transfers of energy from the wind wave frequencies to long waves with periods of the order of several minutes....
Wave Forecasting for Construction in Mobile Bay
Wave heights were forecast for day-to-day pipeline construction operations in the Main Pass area of Mobile Bay. A low-cost forecasting procedure was developed using the wave generation...
A Design Manual for Coastal Fluidization Systems
This paper summarizes a recently completed design manual on fluidization systems to manage sand in the coastal environment for sand bypassing at inlets and harbor mouths and for creating...
Robust Approach to Wave Runup Calculation
Wind wave runup on a natural beach is examined for the case of an irregular wave forcing function. A pragmatic approach to the calculation of the runup time series and the corresponding...
Tackling Trapped Sediments
Crater-sink fluidization has been used to recover sediment from harbors for the past couple of decades. Can this method bypass sediment around dams and return it to eroded beaches, solving...
Wind Cross-Spectrum Effects on Long-Span Bridges
This paper discusses current analysis for long span bridge response based on wind components. The authors summarize the development of techniques which take such components into account,...
