Abstract
Geocells are lattice-shaped reinforcement materials used to reinforce the ground, such as to deal with soft ground. Installing geocells in the base course can distribute traffic loads over a wide area and reduce stress. However, a clear design method for geocell installation has not been established. In order to promote the use of geocell-reinforced substrates in the future, it is essential to study the reinforcement mechanism of geocells and propose a design formula that can accurately evaluate the reinforcement effect. In this study, an experiment using a model was conducted to understand the range of stress distribution in the base course when geocells are installed. Based on the results, a base layer thickness calculation formula was proposed, and the accuracy of the proposed formula was examined.
