Trial Lake Dam Reconstruction
Trial Lake Dam is located in the Uinta National Forest in Central Utah at an elevation of about 10,000 feet. The dam is 50 feet high and stores 1,700 acre-feet of water for downstream...

Dam Safety: A State's Perspective
The State's role in the rehabilitation of dams is discussed. The author presents a national picture of dam safety, describes some dam failure statistics on type of dams that have failed,...

Seismic Safety Modification of an Old Earthfill Dam
Chollas Dam was built as a water supply reservoir for the City of San Diego. The reservoir is no longer a part of the municipal water system but has been operated since 1966 as a recreational...

Hydration Properties of Shotcrete with an Accelerator Based on Calcium Aluminate
A new powder-type accelerator based on calcium aluminate has been used for shotcrete in underground construction. This accelerator can be applied to all types of shotcreting. The shotcrete...

To the Limits of Shotcrete Linings
In the 1950s for the first time shotcrete was used because an essential support measure to guarantee the stability of an underground opening in Austria, Detzelhofer (1). Since that time...

Single-Shell Shotcrete Method
On a 60-m-long test stretch in the course of the construction of the Munich Subway the single-shell jointless shotcrete method was employed. In this case the standard cross section of...

Lattice Girders for Shotcrete Support
Lattice Girders complement the use of shotcrete for underground support by reducing the risk involved with using shotcrete alone for temporary or permanent lining of a tunnel or shaft....

Application of Shotcrete for Ground Support at Inco Mines
In 1989, shotcrete was first successfully introduced for ground support in production areas at Frood Mine. Until then the only successful application of shotcrete had been in major permanent...

Supply-Side Solutions
Although the crumbling bridge infrastructure has received much attention in the press and the engineering community over the past few years, the number of structurally deficient bridges...

Photogeologic Reconnaissance of X-Tunnel at Little Skull Mountain
An underground structure known as X-tunnel was investigated for the viability as an underground deep based missile system that included the capability to maintain survivability following...

A Note on Physical Modeling Approach for Assessment of Excavation Techniques
With the growing interest in utilizing underground space, the need for quantitative and qualitative assessment of excavation techniques to dictate the best choice for mining is now becoming...

Role of Fracture Zones in Controlling Hydraulic Head and Groundwater Flow?Experience from Site Characterization Program in Finland
The preliminary site investigations for the final disposal of HLW produced by TVO have been carried out during 1987 - 1992 in five areas. All the areas consist of Precambrian crystalline...

Prioritization of ESF Testing and Integration with Design and Construction
The developmental strategy for underground site characterization testing in the Exploratory Studies Facility (ESF) of the Yucca Mountain Site Characterization Program is outlined. The...

Modeling of the Ventilation for Emplacement Drift Re-Entry and Rock Drying
Different ventilation scenarios were analyzed for a hot repository with a 114 kw/Acre heat load, to determine the time required to cool a drift to the point where the temperature of the...

Structural Character of the Ghost Dance Fault, Yucca Mountain, Nevada
Detailed structural mapping of an area that straddles the southern part of the Ghost Dance Fault has revealed the presence of several additional subparallel to anastomosing faults. These...

Geohydrologic Data and Models of Rainier Mesa and Their Implications to Yucca Mountain
The geohydrologic data collected at Rainier Mesa provide the only extensive observations in tunnels presently available on flow and transport in tuff units similar to those of a potential...

1992: When Things Began to Move at Yucca Mountain
This paper examines progress made on the Yucca Mountain Site Characterization Project (YMP) during 1992 and continuing into 1993. In addition, it discusses and describes design work on...

The Results of Near-Field Thermal and Mechanical Calculations of Thermal Loading Schemes
Two waste emplacement schemes, borehole and in-drift, are under evaluation as potential repository drift geometries for the Yucca Mountain Site Characterization Project. Calculations were...

Safeguards and Security Issues at the MRS Facility
The U.S. Department of Energy's (DOE) Office of Civilian Radioactive Waste Management (OCRWM) is responsible for disposing of the nation's high level radioactive waste in a way that ensures...

Structure of Crater Flat and Yucca Mountain, Southeastern Nevada, as Inferred from Gravity Data
Existing gravity data in the vicinity of Yucca Mountain and Crater Flat have been examined to determine if these data support only the caldera model or if they support other geologic models...
