12、e of new and emerging technologies through the publication of the Emerging Technology Series. This series presents information and recommendations based on avail-able test data, technical reports, limited experience with field applications, and the opinions of committee members. The presented inform
13、ation and recommendations, and their basis, may be less fully developed and tested than those for more mature technologies. This report identifies areas in which information is believed to be less fully developed, and describes research needs. The professional using this document should understand t
14、he limitations of this document and exercise judgment as to the appro-priate application of this emerging technology.Fiber reinforcement has emerged as an alternative to traditional reinforcing bars and welded wire mesh reinforcement for precast concrete tunnel segments. Due to significantly improve
15、d post-cracking behavior and crack control characteristics, fiber-rein-forced concrete (FRC) segments offer advantages over tradition-ally reinforced concrete segments such as saving cost and reducing production time while developing a more robust product with improved handling and long-term durabil
16、ity. Specific guidance on the design of fiber-reinforced precast concrete tunnel segments is needed for this emerging technology. This document offers general information on the history of FRC precast segments from tunneling projects throughout the world; a procedure for structural analysis and desi
17、gn based on governing load cases; and a description of the material parameters, tests, and analyses required to complete the design. The proposed guidelines are based on the knowledge gained from experimental research, analytical work, and the expe-rience gained on numerous FRC precast tunnel projec
