Monitoring of Structures During Repair of Underground Utilities
A collapse of underground utilities at a power plant required the constant monitoring of the surrounding structures during excavation and replacement of the damaged pipes. A computer-based...

A Near-Term, Long-Duration, Lunar Outpost Design
The design of a long-term human outpost on the Moon will require shielding from not only solar proton and galactic cosmic radiation but also from micro-meteoroid and meteoroid strikes....

Soil Mix Walls in Difficult Ground

Ground Movements from Model Tieback Wall Construction

Preparation of Bid Documents for Dredging/Excavating Contaminated Sediments, Soils and Marsh Deposits at the Marathon Battery Superfund Site Cold Spring, NY

Design of Shotcrete Support from the Rock Mechanical Viewpoint
When designing tunnel support the key question is to determine the loading conditions resulting from the deformation of the rock mass during and after excavation. Principle views are given...

Design and Application of Integrated Shotcrete Linings for Underground Openings in Weak Rock Masses
Tunnels and caverns excavated in weak rock masses require special consideration in terms of shotcrete lining design. Shotcrete as a support medium for weak rock provides major benefits...

Active Tunnel Design—A New Concept for Predesign, Contractual Lay-out and Construction Management
Active tunnel Design is a new concept for design, layout of specification and contract, and for construction management of tunnels and underground carverns. Investigations yeild more information...

Austrian Guideline and National Report on the Use of Shotcrete
The purpose of this guideline is the standardization of quality and a uniform procedure for the production and testing of shotcrete from the technical and engineering point of view. In...

Site Measurement of Shotcreting Dust
Shotcreting is broadly used today as an excellent lining system, which enables to assure rapidly the stability of excavated rock surface. This system however leaves room for improvements...

Block Dynamics Modeling in Support of Seismic Design
The behavior of an underground excavation is usually characterized by stresses and displacements which develop around the excavation as a result of prevailing field conditions. For conventional...

Use of Shotcrete on Recent Tunnel Projects in the South and East, USA
Shotcrete and rockbolts are now the primary method of ground support for the majority of rock tunnels in America. This paper describes the use of shotcrete and some of the shotcreting...

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...

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...

Yucca Mountain Site Characterization Project Exploratory Studies Facilities Construction Status
This paper discusses the progress to date on the construction planning and development of the Yucca Mountain Site Characterization Project (YMP) Exploratory Studies Facilities (ESF). The...
