| Abstract: | Interfacial interactions between fiber reinforcement and soil play an important role in reinforce benefit.Understanding the interfacial mechanical behavior is helpful to apply effectively the fiber reinforcement in geotechnical engineering practice.The objective of the present work is to study the interfacial micro-mechanical behavior of discrete polypropylene fiber reinforced soil.Three soil types(fiber reinforced raw soil,cement soil and lime soil)commonly used in the field were taken into account.The evo... |
