Adopted method of laboratory test to study basic mechanical properties of GFRP, based on the background of the construction of Beijing Metro Line 16 bid package 03, in the course of the origin and reception of the shield, by means of replacing reinforcing bars to GFRP bars, the shield cuts the retaining structure directly ,dispensing with the process of manual cuttingto achieve accessibly origin and reception of the shield. From four aspects of the safety quality, economic benefits, ecological civilization, technological progress,compared with the traditional method of origin and reception methods the new technology is analyzed to illustrate the social benefits of it.
