Many slope stability projects are not getting the full benefit of instrumentation because there is no funding for long term monitoring, according to Kingston University’s Eddie Bromhead.
Speaking at the annual Slope Stability conference in London yesterday, Bromhead said in his opening address that the value from instrumentation comes from long term readings. “There is too much focus on getting information in a short space of time and this does not allow trends to be detected that could benefit the design process,” he said.
“The cost of the instrumentation should be matched with equal funding for reading and another tranche of equal funding for the analysis.”
Bromhead went onto say that there is too much focus on computer analysis in geotechnics and less and less use of expert judgement. He also urged engineers to respect that ground is not homogeneous and stop referring to the Gault Clay, the London Clay and the Lias and respect the variation that occurs within the geological formations.
