The Effect of Elastic Tube Strength on the Pressuremeter Modulus
A study of the effect of elastic tube strength on the pressuremeter modulus is presented. By using probes with different strength tubes in adjacent boreholes, a comparison of pressuremeter moduli was made. While the tubes varied in their resistance to inflation, the effect on the modulus was negligible. It is suspected that the effect might be more significant in very soft soils. The sensitivity of the pressuremeter was not affected by the changing elasticity of the tubes. The unusual shape of the inflated probe was noted.
