巨型植物群(即非常高或巨大的树木)的基础系统长期以来一直被用作现代浅基础和深基础的类比。太沙吉引用树木作为基础和桩的模型。然而,天然地基系统的拓扑结构、形式、材料、分布和功能与岩土工程师设计和建造的浅地基和深地基系统几乎没有共同之处。这些天然地基系统具有弹性、坚固性和适应性,是新一代人为地基系统和对土-结构相互作用的新理解的理想模板。在努力进一步仿生岩土工程,本文将提出一个审查的实际拓扑结构,形式,材料,分布和功能的巨型植物群的基础,突出与人造基础系统,材料和设计的关键区别。本文将消除关于这些自然结构的常见神话,让工程师深入了解它们在复杂和极端载荷下的性能。将突出几个关键物种,每个物种的基础系统的独特方面突出。几个天然地基系统的现场测量和观察包括在文件中,以突出这些显着的系统的最新研究结果。
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.
