Strip Foundation on Geogrid-Reinforced Clay
Laboratory model test results for the ultimate bearing capacity and allowable bearing capacity at various settlement levels conducted on a strip foundation supported by geogrid-reinforced...
Geocell Mattress Effects on Embankment Settlements
Laboratory investigations and finite element analyses of geocell mattresses beneath embankments were performed to determine the effect of such mattresses in reducing settlements. Eight-foot...
Velocity Control Rings for RC Pipe on Steep Slopes
This paper discusses the use of internal concrete rings to reduce velocity and concrete erosion for reinforced concrete pipes on steep slopes in the Southern California area....
Chicago's Waterfalls
The 1994 Outstanding Civil Engineering Achievement Award goes to successful implementation of an elegantly simple idea: aerate sluggish water by letting it fall through man-made waterfalls....
Alternatives for Overtopping Protection of Dams
Prepared by the Task Committee on Overtopping Protection of the Hydraulics Division of ASCE. This report summarizes the results of an inventory and...
Computer Calculations Speed Tunnel-Lining Design
A computer program handles the computations and simplifies a method that sets forth the vast amounts of tunnel concrete lining design information in a single diagram. Using the principle...

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,...
High-Grade Concrete for the Single Permanent Shotcrete Lining Method
With the single permanent shotcrete lining method in underground construction in rock, a shotcrete layer placed subsequently to the application of the supporting shotcrete replaces the...
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...
Development of Mechanized Wet Mix Shotcrete Application in Norwegian Tunnelling Industry
From 1971 to 1980 wet mix shotcrete won the Norwegian market 100%. In the same period hand held spraying was replaced by hydraulic manipulators. From 1980 to 1986, steel fibre use increased...
The Influence of Water Glass on the Technological Parameters of Shotcrete
Shotcrete used in tunneling must follow a clearly defined early strength development in order to comply with stresses from rock deformations and drilling and blasting. Accelerators are...
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...
Fire Testing of Shotcrete Samples in a Small Furnace
The fire resistance behaviour of 8 shotcrete samples were investigated in a laboratory furnace applying ISO 834 standard test. Shotcrete was applied on 20 to 30 cm thick granite slabs...
Use of Steel-Fiber Reinforced Wet-Mix Shotcrete in Extreme Rock-Bursting Conditions
If the stresses close to tunnels or caverns exceed the capacity of the surrounding rock, rock-bursting might start. When tunneling in such rock conditions the need for a safe, quick and...
