Open standpipe piezometer Service

open standpipe piezometer
Piezometric pressures influence the strength of soil or rock. Critical pore water pressures should be estimated during design of embankment fills and other structures. During construction, piezometers can be installed to monitor the pore water pressures. The dissipation of the pore water pressure over time is used as a guide to consolidation rate. Thus, piezometers can be used to control the rate of fill placement during embankment Continue reading “Open standpipe piezometer Service”
