A Theoretical Study of Pore Pressure Generation and Dissipation Around the Pressuremeter

Source

Results of finite element analyses of self-boring pressuremeter tests in theoretical two-phase soils are presented. In particular, pore pressures generated during an initial small strain expansion stage and their dissipation during a subsequent consolidation stage are analysed for different pressuremeter lengths. It is shown that the basic results of the reference expansion test are not affected by partial drainage. Pore pressure measurements during volume holding tests are proven to yield satisfactory values of radial coefficient of consolidation using the elastic plane strain solution of Randolph and Wroth (1979), even for the shortest probes. The self-boring pressuremeter thus provides, for offshore practice, interesting basic soil parameters measured in-situ, besides the limit expansion pressure for direct design of deep or shallow foundations.
