Bio-Inspiration through Tree Root Pullout Tests for Innovative Anchorage Design
Application of bio-inspired design to geotechnics is still in the early stages of development. Bio-inspiration methods employed herein are centered on advancing understanding of biological systems from form-level (physical structures), to behavior-level (processes and mechanisms), to principle-level (why the forms and behaviors are or are not effective). This paper details the connection from the study of natural root system forms and behaviors, to direct study of the biological analog, to extraction of principles for development of engineering designs. Ten three-year-old fruit trees with different rootstocks were subjected to vertical pullout tests in the UC Davis Plant Science Department teaching orchard. Measurements during pullout testing included load, displacements, ground accelerations, and photos for 3D model development using photogrammetry. Analysis focused on the progression of failure mechanisms in the root systems through analysis of load, displacement, and distributed accelerometer measured time histories. Results show that trunk displacements associated with peak resistance are smaller than those associated with mobilization of much of the distal root system. Methods for improving strain compatibility will be important for design of nonlinear and branched foundation systems.
