Geocell-Reinforced Lateral Support for Anchoring Structural Foundations
With the advancement of portable quick install structures, there is an observed increase in demand for anchoring light structural foundations to natural grounds. For example, installation of floating fence needs pounding rods anchored to the existing subgrade at defined intervals. Even anchoring temporary portable foundations can leave permanent footprint on environment. Particularly, when the existing natural ground is soft, the structural footprint of the foundation anchors can interfere larger area requiring extra material to be shipped, which ultimately lead to increased carbon emission. Considering foundation designs on weak natural existing organic soil, long term stability of structure becomes a challenge. In such scenario, hybrid-designs with geocell reinforced stratum could be a viable alternative solution to the conventional design. This sustainable solution is economical, readily available, and easy to install. Over the past decade there has been substantial research on ground reinforcement technology with geocell. Overwhelming stress related study on geocell has been on lateral stress distribution for vertical load. However, when it comes to anchoring rods or pile foundations, the critical forces are lateral. Building the topsoil structure reinforced with high modulus and high strength polymeric geocell, filled, and compacted with naturally available granular material, plays a significant role in improving foundation design capacity. This innovative hybrid-design technology can reduce conservatively 25% of pile sectional area as compared to conventional design for specific assumed soil conditions. This paper discusses the innovative approach to optimize deep foundation designs using geocell reinforced soil.
