International and Educational Aspects of Watershed Management
International donor agencies involved in furnishing technical and economic assistance for increasing food and fiber production are focusing their attention towards rain-fed agricultural...

Embankment Seepage Control Design and Construction
For seepage control features of embankment dams, design criteria and construction practice is reviewed as it is reflected in the experience of the U. S. Army Corps of Engineers. The generally...

Seepage Control at Cochiti Dam, New Mexico
Significant design data, design assumptions and computations, and performance of the seepage control features provided at Cochiti Dam are summarized in this paper. The dam is a rolled...

Soldier Creek Dam Foundation Drainage
A possible mode of failure for Teton Dam, piping of erodible core material through unsealed foundation joints, was also concluded as being possible at Soldier Creek Dam, Utah. Evaluations...

Seepage in the Unsaturated Zone: A Review
This paper briefly reviews the procedures whereby the seepage rate, depth of penetration of nonreactive pollutants, and the depth of the wetting front can be calculated when the assumption...

Containment of Textile Waste Using a Geomembrane
A wastewater treatment plant for a textile mill incorporated two 2. 7 million gallon aeration ponds which had originally been lined with clay. The clay liner leaked and caused the formation...

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...

Permanence of Chemically Grouted Sands
Test specimens were prepared with one of three uniformly graded sands of a fine gravel and injected with one of five silicate or two polyacrylic grouts. The polyacrylic grouts showed no...

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...

Embankment Foundation Densification by Compaction Grouting
Compaction grouting is an attractive alternate for in-place densification of liquefiable soils below existing structures. Compaction grouting application concepts and procedures are presented...

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...

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...

Load-Carrying Capacity and Remaining Life of First-Built Composite Girder Bridge in Japan
Kanzaki Bridge, Osaka, Japan, was the first steel-concrete composite bridge built in 1953 to carry the Osaka Prefectural Road over Kanzaki River. The bridge was removed in 1978 after 25...

Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...

The Eurocodes and Shrinkage in Composite Beams
The two parts of this paper relate to different aspects of design procedures for composite structures of steel and concrete. First, recent developments in the coordination of the eight...

Experimental Investigation of Composite Rigid Frames
According to the series of tests conducted by the authors on composite rigid frame models, the compressive principal stress in the steel web plate at the corner panel was considerably...

Mixed Systems: Past Practices, Recent Experience, and Future Direction
A comparison is made between composite column capacities derived from the authors procedure utilizing the ACI (America Concrete Institute) code requirements, and previously published semi-empirical...
