The Company EPC (elastoplastic concrete) has developed a series of new synthetic fibers: Barchip. It a good alternative to steel bars, because of its better durability, fire resistance and low carbon emission, etc.. EPC company desires that the synthetic Barchip can be applied in the subway tunnel construction in Shanghai. Therefore, this paper is intended to replace the steel bars with Barchip in tunnel lining. This article describes the various Barchip reinforced concrete test results, as well as synthetic fibers’ other engineering application examples. The design in this paper is based on a typical Shanghai geological condition. According to the results of real beam test from EPC and design guide (RILEM TC 162-TDF), a model of Barchip reinforced concrete was built in the Software ATENA. The model of ground and the tunnel lining was simulated in the Software. The results showed that the tensile and compressive stress and crack control etc. meet the engineering requirements. Barchip synthetic fibers can be used in the construction of the Shanghai subway tunnel lining.
