The Use of Low-Cost MEMS Accelerometers for the Near-Surface Monitoring of Geotechnical Engineering Systems
The urban underground environment is under continuous development as the infrastructure ages and new technologies are added to the existing networks. Design, construction, installation, and repair in this ever-changing environment can benefit significantly from high-resolution imaging to acquire adequate subsurface characterization. This paper documents the development of MEMS accelerometers as a low-cost alternative sensor to geophones and piezocrystal accelerometers for monitoring wave propagation in soils. The experimental study includes an evaluation of limitations and the development of a simple packaging system for the broad application of MEMS in the geoenvironment. The calibrated accelerometers are used to monitor elastic wave propagation for the evaluation of changes in the effective state of stress within a 1g model of a braced excavation. The experimental program captures the effects of load and deformation as elastic waves propagate behind a sheet-pile system. Results hint at the development of long-term non-destructive monitoring systems for the diagnostics and control of geotechnical processes.
