An Examination of the Foundations of Mega-Flora: Implications for Biomimetic Geotechnics
Publication: Geo-Congress 2020: Biogeotechnics (GSP 320)
ABSTRACT
The foundation systems of mega-flora (i.e. very tall or large trees), have long been used as an analogy for modern shallow and deep foundations. Terzaghi referenced trees as the model for footings and pilings. However, the topology, form, materials, distribution, and function of the natural foundation system have very little in common with the shallow and deep foundation systems that geotechnical engineers design and construct. These natural foundation systems are resilient, robust, and adaptable; ideal templates for a new generation of anthropogenic foundation systems and new understanding of soil-structure interaction. In an effort to further biomimetic geotechnics, this paper will present a review of the actual topology, form, materials, distribution, and function of mega-flora foundations, highlighting key differences with man-made foundation systems, materials, and designs. This paper will dispel common myths about these natural structures, giving engineers insights into their performance under complex and extreme loads. Several key species will be highlighted, with unique aspects of each species’ foundation system highlighted. Field measurements and observations of several natural foundation systems are included in the paper to highlight recent findings about these remarkable systems.
