Abstract:
Shotcrete has proven to be useful on many tunnel projects both for initial support during construction and for permanent support. This paper describes its use in large shallow underground openings in rock and presents several examples which indicated the effect of geology on shotcrete behavior.

[An outlined article] If shotcrete is being considered for use in support of an underground excavation, a problem of ground support has been encountered, or a potentional problem is anticipated. Identification of the problem is the first step in its solution. Most problems of ground support can be placed in one or more of four classes. . .

"I should like to describe rather briefly the shotcrete design practices that have been followed by the Bureau of Relclamation. In doing this, several different uses of shotcrete in tunnels will be instanced. Reasons why advancements toward the use of the "New Austrian Tunneling Method" have not been more rapid in this country will be discussed and finally some mention of the outlook for use of concrete in future tunnels.

An economic need necessitated the experimentation and development of a high production nozzle that had a low maintenance factor. With commercial nozzles, as production increased, the maintenance factor accelerated and the nozzle itself proved to be a limiting factor for higher production. The shotcrete was used for rock support in an 18' horseshoe tunnel and was used primarily by itself to make the rock support itself in lieu of using shotcrete with rock bolts or steel sets. All of our equipment is rail-mounded with a sliding floor, and a "California Switch" in each heading.
