Experimental Research on Strength of GFRP Bars in Shield Engineering

Abstract:

Subway stations or shield wells are often built using steel reinforced concrete supporting structure materials. These concrete retaining structure materials must be destroyed before launching and receiving of shield, so, some security risks may arise during destroying, and time limit for project may be longer, and the structure strength may be weakened; there are the same problems in crossing the existing subsidiary structure. In the supporting structure, concrete supporting structure materials have been partially substituted by GFRP bars in shield engineering in the world. In order to study the mechanical properties of GFRP bars deeply, experimental research on strength of GFRP bars have been made, and some relation shapes between stress and shear strength have been discussed; all of these are expected to make some basis for the design of GFRP concrete in shield engineering.
