Cable-Stayed Convention Center
Big convention center brings big money. For that reason, officials in Kansas City, Mo. hoped to double the size of the Bartle Hall Convention Center. Little available land, however, surrounded...

Seismic Retrofitting: Spending to Save
Seismic retrofitting work is most often concerned with saving lives. But in cases of infrastructure, or historic structures, saving the structure, and making sure that it can operate after...

Fast-Track Stadium
The project team selected to design and construct Egypt's cable-supported Cairo Stadium Indoor Sports Complex in late 1989 faced a hard-and-fast deadline. Just 18 months later,...

Taming the Urban Underground
When designing and installing excavation support systems at a city construction site, be prepared to deal with the urban jungle. Tunnels and utility cables and pipes clog the underground,...

Masonry Carries the Load
Engineers frequently have preconceived notions about building materials. Masonry, for example, is commonly selected by architects for its color and texture, rather than by engineers for...

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...

Guidelines for Shotcrete Support in Hard Rock
The writer is working on a handbook on shotcrete in hard rock. The work is sponsored by the Swedish Power Board, Development Division. The main contents are: Choice of shotcrete support...

Wet Mix Shotcrete Used in Subsea Tunnel Environments
To reject the claim that the use of accelerator in shotcrete reduces the compressive strength with time, lately cored samples were taken from an 18 to 19 years old concrete. A wet mixed...

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...

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...

Advances in Shotcrete Technology for Support of Underground Openings in Canada
This paper presents a broad overview of the state-of-the-art of shotcrete technology for support of underground openings in Canada. Advances in shotcrete technology such as the introduction...

Design of Shotcrete Linings at the Channel Tunnel
Shotcrete is one of the essential support elements of tunnels driven according to the principles of the New Austrian Tunnelling Method (NATM). Whereas originally the NATM was mainly based...

Construction of Shotcrete Linings Channel Tunnel
Without the use of shotcrete and the flexibility it offers in terms of tunnel profile, economy and speed of tunnelling, the project would certainly not be as far advanced as it is at present....

The Introduction of Steel Fibre Shotcrete to Underground Cavern Support in Taiwan
The Mingten project is located in a sheared, sandstone rock mass near a regional fault. The design philosophy introduced steel fibre shotcrete as a permanent cavern support in Taiwan....

A Review of Sprayed Concrete Linings Adopted at Dinorwig Power Station
Sprayed concrete was adopted extensively as one element of both temporary and permanent rock support during the construction of the 1800 MW Dinorwig underground power station in North...

Network Management Using GIS
This paper is concerned with the opportunities that arise from combining digital highway networks, relational databases, GIS technology, specialist application software, and workstation...

Use of Geographic Information System for Transportation Data Analysis
Origin-destination (O-D) survey data have been usually applied to identify travel characteristics for transportation planning activities. Travel forecasting models are also validated against...
