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 Uses of Reinforced Shotcrete in Underground Projects in Canada
The first use of steel fibre reinforced shotcrete (SFRS) in Canada was using the wet-mix process in the support of deteriorated ground in 80 year old railway tunnels in the Fraser Canyon,...
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...
Technical Note: STC-40 Shotcrete Adhesion In Situ Tester
It is essential that the shotcrete when reinforcing the rock mass achieves a good adhesive bond to the rock surface. The strength of that bond can be controlled by pull out testing either...
Route 5: Steel Fibre Shotcreting in Shing Mun Tunnels Hong Kong?Specifying for Innovation
The Shing Mun tunnels form the central 2.6 km length of the Route 5 Highway connecting Tsuen Wan and Sha Tin New Towns, Hong Kong. The crossing of one of the areas was particularly difficult,...
Network Management Using GIS

A Microcomputer Program to Evaluate Low Cost Modifications on Urban Freeways
This paper presents a user-friendly, menu-driven microcomputer program, RAMP, for analysis and evaluation of freeway ramp junction level of service. RAMP automates the approximation procedure...
Florida's New Toll Facilities Model
Florida's Turnpike provides a system of user-financed limited access toll highways meeting important transportation needs in the State of Florida, while protecting the interests of its...
Policy Options and Highway Capacity Needs
One of the recurring criticisms levelled against FHWA's Report to Congress on the Status of the Nation's Highways is that the Report does not go far enough in examining the implications...
Better Ways to Update Trip Matrices
Updating origin-destination (OD) trip matrices usually involves considerable survey costs, so engineers are often forced to use dated OD information, which can seriously undermine the...
Synthesis of Traffic Signal Timing for the Highway Capacity Manual Planning Analysis
The 1985 Highway Capacity Manual (HCM) provides a technique to analyze the operation of signalized intersections. The Highway Capacity Software (HCS) is a microcomputer package that faithfully...
An Expert System Analysis of the Signal Operational Analysis Package Results
An expert system is a type of artificial intelligence program that captures the human knowledge which is involved in making a decision. Expert systems are very suitable for solving problems...
