Abstract

For steep slopes with difficult access or slopes in a corrosive environment, there are various problems associated with the use of conventional steel reinforcement bars as soil nails. For loose-fill slopes or clay slopes, the development of adequate nail bond strength is another practical issue that should be considered. Carbon fiber–reinforced polymer (CFRP) and glass fiber– reinforced polymer (GFRP) in several forms and installation methods have been studied as the alternatives to the classical steel bar. Extensive laboratory tests on the materials and field tests on different types of soil nails with various methods of installation have been carried out in Hong Kong, Korea, and Australia. Test results support the use of these materials with an innovative installation method as soil nails under different geological conditions, and the suitability and performance of these materials under different conditions are assessed in the present study.
