Lateral Load Deflection Behavior of Recycled Plastic Pin Subjected to Field Load Test
Publication: Geo-Congress 2024
ABSTRACT
Geo-structures, like MSE wall constructed over weak soil, are prone to base sliding failure, which causes failure in the long run. Recycled plastic pins (RPPs) can be a viable and sustainable solution for increasing the lateral resistance of the foundation system. The objective of the present study is to evaluate the lateral resistance of RPPs in terms of load deflection behavior by conducting field load tests. In this study, RPPs of two different sizes were driven into high plastic clay at three different embedment depths and were laterally loaded to failure or until excessive deflection occurred. Based on the load deflection behavior obtained by the field load test results, the 10 cm-by-10 cm RPPs had lateral load bearing capacity ranging from 16 to 28 kN. On the other hand, lateral load bearing capacity of 15.24 cm-by-15.24 cm RPPs was found to be in the range of 29 to 40 kN. It was observed that lateral load capacity increased 40% to 80% as RPP size increased, and deflection increased from 20% to 50% as embedment depth decreased.
