TL;DR: In this article, a nonintrusive measuring system is proposed to monitor the integrity of ground anchor support for utility poles, where the anchor rod with a terminal buried plate attached can be measured periodically with an accelerometer.

TL;DR: In this paper, the authors investigated the vibration isolation efficacy of the geocell reinforcement through the numerical simulation technique and found that the use of geocells reduce the resonant displacement amplitude by 56% and increase the natural frequency of the soil foundation system by 42% as compared to the unreinforced bed.
Abstract: The present study aims to investigate the vibration isolation efficacy of the geocell reinforcement through the numerical simulation technique. The explicit finite difference package, FLAC3D was chosen for the dynamic simulations. Initially, the developed numerical models were validated with the results of the vertical mode block resonance test. The behaviour of soil bed and concrete footing was simulated using Mohr–Coulomb and linear elastic models, respectively. The geocell was modelled using two techniques, namely Equivalent Composite Approach (ECA) and Honeycomb-Shaped Approach (HSA). The results revealed that the use of the geocells reduce the resonant displacement amplitude by 56% and increase the natural frequency of the soil–foundation system by 42% as compared to the unreinforced bed. As compared to the experimental results, the ECA modelling technique was found to overestimate the improvement in resonant frequency and the reduction in displacement amplitude by 4% and 10%, respectively, in the presence of geocells.

TL;DR: A piezo-active composite with 0-3 connectivity represents a system of isolated inclusions (either FC or ferroelectric SC) in a large matrix that may be either a polymer or FC as discussed by the authors.
