DILATOMETER LATERAL STRESS MEASUREMENTS IN SOFT SENSITIVE CLAYS

Results from self-boring pressuremeter (SBPM) and dilatometer (DMT) tests at sites in Portsmouth, New Hampshire, and at Hamilton Air Force Base, California, are compared in terms of total lateral stresses. Site-specific correlations for soft sensitive clays between the dilatometer initial lift-off pressures and the range of self-boring pressuremeter horizontal stresses are observed, and it appears that the SBPM can be successfully used to calibrate the DMT. Results from lateral stresses measured at the end of DMT total stress dissipation tests are in close agreement with upper bound results from the SBPM.
