Program for Large-Scale Tests on Prototype Tunnel Supports
Programs for the development and testing of two promising innovative tunnel support systems are presented in this report. One new support system is a lining, capable of being slipformed, composed of wire fiber reinforced concrete made with high, very early strength regulated-set cement. Recommendations are given for: studies on mix design, practical pumping tests, analytical ground-structure interaction studies, and large-scale tests performed on prototype linings 10 ft in diameter. The results of tests on wire reinforced concrete are to be compared to the results of tests on conventional reinforced concrete. A program for analysis and testing of improved steel sets fabricated from tubular box sections is also presented. (Author)
