摘要	Ma Quan Ying Station (Xiangjiang Bei Lu Station) similar to Cui Ge Zhuang Station on Beijing Subway Line 15 set air passage for tunnel boring machine. Tunnel boring machine on right line has through air passage safety, and cannular shield have not been removed. Tunnel boring machine on left line from the air passage are 255 circuits (306 m), for the speed of tunnel boring machine is 20 similar to 30 circuits pre day, start monitoring the effect on the second lining structure during tunnel boring machine digging process. Use of advanced fiber Bragg grating sensor, and with a Si425 Bragg Grating Demodulator as a data collector, by corresponding formulas calculate the micro-strain of points on wall, to study the second lining structure status when under press during tunnel boring process. In the final 100 meters, on the 32 monitoring sites for monitoring the stress and strain. For the other tunnels provide a basis for inference.
