This paper describes the potential of wireless sensing networks to improve geotechnical field monitoring and the use of wireless sensors in two on-going geotechnical research projects. Both studies are Network for Earthquake Engineering Simulation Research (NEESR) projects funded by the National Science Foundation (NSF). The first project focuses on the phenomenon of timedependent changes in the state and properties of recently deposited, disturbed, and/or densified saturated sand deposits. Wireless sensors are being integrated with pore pressure transducers and accelerometers to record the response of the deposits undergoing explosive compaction, vibrocompaction, and vibroseis shaking. In the second project, wireless sensors are being used to monitor the performance and health of buried pipelines crossing a fault plane undergoing differential movement. The focus is on concrete pipelines that are often used in water distribution networks. There is great potential for use of wireless sensors and wireless sensor networks in geotechnical fieldwork because of their relatively low cost and easy adaptation for use on construction sites and in urban areas because their placement is not restricted by cables.
