“…They have many advantages compared with steel, including a higher strength-to-weight ratio, better corrosion resistance and low electromagnetic properties. GFRP components have been widely used in geotechnical engineering in recent years (Sen et al, 1991;Iskander and Hassan, 1998;Weber et al, 2006;Ashford and Jakrapiyanun, 2001;Xue et al, 2011;Chai et al, 2011). Many researchers studied the performance of GFRP soil nails and their difference with steel soil nails.…”

“…Fiber‐reinforced‐polymer (FRP) composites offer a better environmental resistance and are light‐weight, high‐stiffness, and more easily designed compared with the steel reinforcements that are currently applied in geotechnical engineering structures . Among the fibrous materials that are available, glass fibers are the most widely used for civil structures because of their low cost . Soil nails and anchors are mainly used under tension.…”

Replacing steel reinforcements with glass fiber reinforced polymer (GFRP) bars has emerged as one of the most promising solutions to the problem of corrosion in geotechnical engineering. Accelerated aging and field tests were conducted to investigate the durability of GFRP bars that were used as soil nails in slope reinforcement. Two types of E‐glass/(vinylester and unsaturated polyester) were immersed in alkaline and saline solutions for 60 d, 180 d and 360 d. Mechanical and physical experiments were carried out to obtain the tensile strength and identify the reasons for damage and strength reduction. A pullout test was carried out after the GFRP soil nails were embedded in a slope for three years. The accelerated aging test results showed that alkaline conditions had a larger influence on the degradation of GFRP bars than did saline solutions and that strength reduction generally occurred at an earlier stage for the alkaline conditions than for the saline solution. The corrosion resistance of an unsaturated polyester bar is much lower than that of the vinylester bar, and the bar diameter has a certain impact. From the field test results, it can be seen that the GFRP soil nails are durable and perform well at the task of supporting a slope. The technology for sensing fiber Bragg gratings (FBG) is very convenient for monitoring soil nails and is suitable for long‐term observation. POLYM.

“…Currently, the researches about GFRP applying to reinforcing concrete mostly come from other countries, and mainly focus on the basic properties of GFRP. For example, Weber et al, 2006, thought the researches on its strength properties is the preliminary step of researches on GFRP reinforcing concrete [6]. In China, researches in this field are in preliminary period, relevant researches are mainly on its application, and, are included less with strength properties of GFRP, especially shear strength properties.…”

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.
