Study on the Application of Fibre Reinforced Polymer Bars in Civil Engineering
The steel anchor reinforcement technology is an important means of geotechnical engineering reinforcement. It can fully mobilize and improve the soil's strength and stability, narrow the dimension of structures, and reduce its weight, significantly saving the engineering materials. With the development and application expansion of anchoring techniques, steel bolt is almost applied in all aspects of civil construction field, such as slope, excavation, mine, tunnel, dam, underground engineering, airports, ports, retaining wall, abutment anchorage and so on engineering constructions and transformations. In this paper, the bearing capacity of glass fibre reinforced polymer (GFRP) and the bond strength in the cement mortar are discussed, and compared with steel bolt. In this paper, the test results of GFRP anchor and steel anchor in the concrete block and rock block in the laboratory and in the field are described. In the experiment, four kinds of GFRP anchors and two kinds of steel anchors were installed in the mass concrete block and the field rock block. The test results showed that the bond strength of GFRP bolt is close to that of steel bolt, and the sliding of GFRP bolt is higher than that of steel anchor, which is mainly due to the lower elastic modulus of GFRP bars.
