New method for full field measurement of pore water pressures
Paper in proceedings, 2018

A cost effective method to measure pore water pressures in mixed granular media is described using 40 miniature MEMS pore pressure transducers. High accuracy in a single point is exchanged for lower accuracy full field measurements adjacent to the strongbox wall. The system is easily de-aired and calibrated due to the fact that the transducers are installed inside the strongbox wall. Additionally, the proof of concept test shows that the transducers are sufficiently accurate for problems with large pressure difference such as consolidation of clay while being subjected to elevated stress levels in the geotechnical centrifuge.
