THE SELF- BORING PRESSUREMETER

The self- boring pressuremeter represents an advance in the state of the art of in- situ testing. While considerable care is required in conducting a self-boring pressurmenter test in soft soil, it appears to be a powerful tool for evaluating soil properties. The Cambridge self- boring pressuremeter is described and its calibration and operation are outlined, followed by discussion on evaluation of test data relating to the Menard pressurementer and the self-boring pressurementer. The determination of the in-situ lateral stress is discussed. For the production of high quality data from the self- boring pressuremeter test, good control is needed over penetration rate, flushing pressure, cutter setting, equilibration period, membrane expansion rate and interpretation method.
