Abutment Seepage at Smithville Dam
After initial filling there was concern for the stability of Smithville Dam when higher than anticipated piezometric levels were experienced in the left abutment foundation. Concern heightened...
A Case History of Leakage from a Surface Impoundment
A manufacturing company constructed a 48-acre (19 hectare), unlined surface impoundment at a site in northern Texas to store wastewater. The site is underlain by unsaturated, alluvial...
Water Balance Approach to Prediction of Seepage from Mine Tailings Impoundments, Part I: General Water Balance Approach
The prediction of seepage from a tailings impoundment requires careful evaluation because the predictions can have significant economic impact upon designs, as well as permit stipulations...
Seepage Control for Embankment Dams USBR Practice
The current Bureau of Reclamation approach to seepage assessment, analysis, and design for embankment dams is described. The advantages and appropriate applications for the analysis programs...
Grout Penetrability
The ability of a grout to penetrate a formation is always a selection requirement for projects in which fracturing is undesirable. The major grout properties affecting penetrability are...
Some Aspects of Analysis and Prediction of Subsidence
A procedure based on the nonlinear finite element analysis was investigated for the prediction of subsidence caused by longwall mining. This paper presents a case study involving predictions...
Application of Displacement of Discontinuity Methods in Underground Mine Design
Displacement discontinuity methods for stress analysis, pioneered by Starfield and Crouch (see, for example, Starfield and Crouch, 1972; Crouch, 1976; and Crouch and Starfield, 1983),...
An Application of Probability to Rock Slope Design
This paper describes the use of probability and statistics in the slope design process. An example is presented of a high rock slope in an open pit mine. This slope is a major concern...
A Combined Limit Equilibrium and Statistical Analysis of Wedges for Design of High Rock Slopes
This paper describes a unique technique developed for the statistical analysis of wedge failures which control the design of high slopes in relatively hard jointed rock masses. Using this...
Probability Applied to Slope Design?Case Histories
A major problem encountered with the choice of an appropriate value for the design probability. Initial experience, obtained during open-pit investigation, suggested that slope geometry...
Fracture Mechanics Analysis of Massive Hydraulic Fracturing Containment
The hydraulic fracturing containment problem is the subject of the present investigation. Unlike previous studies, the interface crack geometry with the correct crack tip singularity was...
Highway Noise: FHWA Requirements and Barrier Design
Since 1973, the Federal Highway Administration (FHWA) has required noise studies for nearly all proposed roadways and roadway improvements that receive federal aid. An overview of these...
Lift Bridge looks Like Sculpture
A lift bridge built in 1926 over the U.S. Canal at Kaukauna, Wis. was replaced by a sleek new lift bridge whose sculptured shape encloses all the machinery within welded steel box sections....
On the Design of Continuous Composite Beams
Methods of analysis and design of continuous composite beams are presented. Numerical analysis is used to determine the effective width of the slabs to be used in design. The influence...
Proposed Design Criteria for Composite Steel Deck Slabs
Composite steel deck slabs have continued to gain popularity; today they are one of the predominant means of floor slab construction in most typical buildings. The term 'composite...
Strength of Biaxially Loaded SRC Columns
The paper presents the results of an experimental study on the elasto-plastic behavior of 'Steel reinforced concrete (SRC)' columns subjected to biaxially eccentric...
Composite and Mixed Construction in Czechoslovakia
Various composite and mixed systems have been used in Czechoslovakia. Special attention is focused on design methods, effective construction, and material savings. Current developments...
Timber Bridge Decks
The portion of the nation's 500,000 bridge decks that are made of timber has been declining for years, as the old timber ones on secondary road bridges are rebuilt, in most...
Critical Load Program
The elastic critical load of a structural frame is a fundamental parameter in assessing its stability. It is an upper bound to the failure load of the frame, in the same way that the Euler...
A Road to Recovery
Inspections of the Golden Gate Bridge revealed that the bridge had localized corrosion near its expansion joints, corrosion of its reinforcing steel, and was severely contaminated with...
