Relation of Channel Stability to Scour at Highway Bridges Over Waterways in Maryland
Data from assessments of channel stability and observed-scour conditions at 876 highway bridges over Maryland waterways were entered into a database. Relations were found to exist among...

Sacramento River Environmental Requirements
Environmental requirements have altered bank protection engineering and construction on the Sacramento River, California. Conflicts between public safety and environmental protection remain...

The Definition of a Short Composite Column
A `short' column in composite construction is defined as one which can be designed for its cross-section strength alone without the need to consider stability effects. An extensive study...

Depth of Cover Surveys for Waterway Crossings
The majority of pipelines cross at least one waterway of some type, especially the interstate lines which from start to end cross numerous bayous, canals and major rivers. These waterways...

Providing People-Mover Access for the Getty Center
An Otis People-Mover System was selected by The Getty Trust to transport visitors to The New Getty Center Museum for the Arts from an entry parking area up a steep hillside to the museum...

Use of Self-Cementing Fly Ashes as a Soil Stabilization Agent
Fly ash produced in the combustion of subbituminouns coals exhibits self-cementing characteristics that can be adapted to a wide range of stabilization applications. Ash treatment can...

Flyash Stabilization of Tropical Hawaiian Soils
A preliminary study of soil improvement/stabilization of several tropical Hawaiian soils with locally generated high quality flyash admixtures has shown tremendous potential as an economical...

Stabilization of South Texas Soils with Fly Ash
The expansive soils of south Texas have traditionally been stabilized with lime or Portland cement. As an alternative, a class F fly ash was tried to stabilize expansive soils obtained...

Enzyme Enhanced Stabilization of Soil and Fly Ash
The purpose of this research was to determine if enzymes could be utilized to increased the strength and stability of soil mixed with fly ash. Samples were prepared with and without the...

The Transistor Psychrometer: A New Instrument for Measuring Soil Suction
The transistor psychrometer is the latest instrument available for the measurement of soil moisture suction. It has been developed over a number of years and is very similar in operation...

Fly Ash for Soil Improvement
This proceedings, Fly Ash for Soil Improvement, contains papers presented at technical sessions of the 1993 ASCE Annual Convention and Exposition...

A Better Grade Of Grade
A new technique for using geogrid reinforcement to construct natural-looking steep earth slopes called landform contour grading helped meet engineering, economic and aesthetic challenges...

Physical Model Testing of Broken Armor Stone
Cracking, breaking into two or more pieces, flaking, crumbling, and abrading may reduce an armor stone to a size where wave action can remove it from the structure causing a local instability....

Stability of Rock Armour Under Random Wave Attack: Performance of Non-Standard Rock Shapes and Gradings
Quarried rock is frequently used to protect coastal and shoreline structures against wave attack. Armour rock specifications generally exclude rock that is rounded or tabular, and gradings...

The 1984 Major Rehab of the Muskegon Harbor, MI South Breakwater: An Extreme Example of Misguided Design of a Stone Structure
It can be inferred from the Shore Protection Manual that the stability of any coastal structure is increased in proportion to the weights of the armorstones. The south breakwater at Muskegon...

Subaqueous Disposal Area Development and Mitigation
Development of subaqueous dikes on soft soils extensively utilized geosynthetics. The design adopted a wide-bermed embankment with high-strength geotextile for tensile reinforcement and...

Dutch Experience on Design of Dikes and Revetments
The increased demand for reliable design methods for protecting structures has resulted in The Netherlands in preparing a set of design guidelines for design of dikes and revetments. The...

Grouting, Soil Improvement and Geosynthetics
The proceedings of the 1992 ASCE Specialty Conference on Grouting, Soil Improvement and Geosynthetics, addresses advances in the state-of-practice, research and technological developments...

Instability of Slopes with Nonassociated Flow
Experimental investigations of the conditions for instability have shown that granular materials may become unstable inside the failure surface. For states of stress below the failure...

Erosion of Steep River Banks and Time Evolution Towards Equilibrium Channel Shape
A numerical analysis of the time evolution of straight river channels is presented. The bed and bank, material is taken to be coarse, non-cohesive and uniform in size. As a result of the...
