Drained Triaxial Response of Clay Reinforced with Natural Hemp Fibers
Soil reinforcement by natural fibers is viewed as a viable, sustainable, and efficient ground improvement technique. An investigation of the published literature reflects a significant effort to study the undrained response of fiber-reinforced clays using triaxial tests. Such tests allow for an assessment of the short-term stability of geotechnical systems that are built with fiber-reinforced clays. For some geotechnical applications for which long term stability considerations govern the design, there is a need for studying the response of fiber-reinforced clays under fully drained conditions. The objectives of the work presented in this paper are to (1) investigate the drained shear strength of clays that are reinforced with natural hemp fibers and which are compacted to different initial water contents and (2) quantify the level of improvement in the drained shear strength due to the addition of fibers. These objectives will be achieved by implementing an experimental drained triaxial testing program on fiber-reinforced clay samples prepared using “static” compaction while changing the confining pressure (20, 100, and 200 kPa) and the moisture content of the clay (18% and 20%).
