Abstract:

For natural clays encountered in the field, the in situ effective horizontal stress may be evaluated from the interpretation of direct measurements by using the self-boring pressuremeter test (SBPMT) or total stress cells or may be evaluated indirectly from other tests such as the dilatometer test (DMT) and piezocone penetration test (CPTU). A review of K sub 0 data summarized from 56 different sites tested by the SBPMT demonstrates that stress history is a predominant factor affecting the magnitude of the in situ geostatic state of stress. For clay deposits that have developed their K sub 0 profile primarily from stress history effects (i.e., mechanical overconsolidation), a simplified cavity expansion theory is used to express K sub 0 in terms of the cone tip resistance and penetration pore water stress obtained during CPTU soundings and the DMT contact stress. Data derived from 17 sites tested by the SBPMT and CPTU and 12 sites tested by the SBPMT and DMT are used to verify the approach.
