Development of Distributed Sensor Pods for Evaluation of Compacted Ground

-Quantification of Ground Stiffness Based on Waveform Distortion of Multipoint Synchronous Vibration Data-

Abstract

In this study, we develop a sensor terminal with multiple and various sensors named sensor pod, which collects various environmental information at a construction site. The sensor pod is equipped with a 3D-LiDAR and a vibration sensor, which can be used to predict the surrounding hazards and evaluate the ground stiffness. In this paper, we introduce a method of evaluating ground stiffness using the waveform distortion of multi-point synchronized vibration data obtained by the distributed sensor pods.
