Reduction of Settlements Using Soil Reinforcement
This paper presents the experimental and finite element method (FEM) of analyses performed to model the use of soil reinforcement for rehabilitation of gantry crane track foundations....

Strip Foundation on Geogrid-Reinforced Clay
Laboratory model test results for the ultimate bearing capacity and allowable bearing capacity at various settlement levels conducted on a strip foundation supported by geogrid-reinforced...

Nonlinear Undrained Lateral Response of Rigid Drilled Shafts Using Continuum Theory
The nonlinear undrained response of rigid drilled shafts under static lateral and moment loading is evaluated within the context of elastic continuum theory. The approximate approach utilizes...

Seismic Settlement of Shallow Footings on Sands
In this contribution, the progressive seismic settlement of shallow footings on cohesionless soils is calculated using a sliding block model. Beyond a critical horizontal acceleration,...

Vertical Displacement Induced in Soil by Conical Shell Foundations
Shells can hold prospect for adoption in foundation engineering only if they can be projected as economical alternatives to conventional flat foundations. Therefore, the initial enthusiasm...

The Tip Displacement of Drilled Shafts in Sands
The design load of large diameter drilled shafts is determined so that the settlements do not exceed the values associated with the ultimate and serviceability limit states. Based on the...

Footing Modulus Near Slopes
A method is described for estimating the footing modulus of shallow spread foundations located near slopes of cohesionless material. The ratio of footing modulus for a shallow foundation...

Load-Settlement Prediction of Footings on Steep Slopes
The use of spread footings on slopes is a common practice in the design of bridge foundations. Footings are generally constructed in the slope or at its crest to minimize the bridge length,...

Reliability-Based Assessment of Corps Structures
Due to the limited amount of funding available for maintenance, rehabilitation, and replacement of aging Corps structures, the director of civil works, Headquarters, U.S. Army Corps of...

Optical Methods for Sediment-Laden Flows
A method of distinguishing between the signals from the liquid-seed particles and sediment particles, while using LDV in sediment-laden flows, is described. The validity of the method...

Impacts of the 1993 Flood on the Mississippi River in Illinois
The 1993 flood has now been recognized as one of the greatest floods on the Mississippi and Missouri Rivers. Its geographical extent included portions of Iowa, Missouri, Illinois, Wisconsin,...

Bearing Capacity of Soils
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 7 This U.S. Army Corps of Engineers engineering manual...

Computer Calculations Speed Tunnel-Lining Design
A computer program handles the computations and simplifies a method that sets forth the vast amounts of tunnel concrete lining design information in a single diagram. Using the principle...

The New Clark Bridge: Saddle-Draped Cables
The new $85 million, 108 ft wide Clark-Bridge replaces a 20 ft wide 1928 truss bridge at Alton, Ill., carrying US 67 over the Mississippi about one mile above the recently completed Lock...

America's Pavements: World's Longest Bathtubs
Pavements are the most unusual structures designed by civil engineers. Water flows through their tops, bottoms and sides but because pavements are relatively flat, flows out again very...

Historic Yorktown: New Bridge Keeps Old Design
In historic Yorktown, Va., the best solution to reconstructing an obsolete 1952 bridge was to keep its unique design while widening it for '90s traffic. Like the original,...

Gateway to Columbus
The Columbus Gateway Arch Bridge is an innovative twin ribbed steel arch structure with a post-tensioned composite concrete deck, transverse post-tensioned composite steel box girders...

Concrete over the Connecticut
The existing Baldwin Bridge carrying I-95 across the Connecticut River between Old Lyme and Old Saybrook, Connecticut, constructed in 1948, is functioning at maximum capacity with modern...

New Developments in Tunnel Lining by Help of Steel Fibre Reinforced Concrete
The combination of single shell structures in tunnelling with the use of steel-fibre-reinforced concrete is decisively able to reduce the costs of tunnel projects. Several variants of...

Using Geographic Information Systems for Traffic Control Inventory Management
Present city traffic control inventory systems lack flexibility, user friendliness, and many have become obsolete because they were originally designed in haphazard ways - thus providing...
