Correct Answer - Option 2 : Shear Modulus

Explanation

  • The pressuremeter test was developed by Louis Menard in 1957. 
  • This in situ test provides the measurement of stress strain response of soils. 
  • It is also used to evaluate the bearing capacity of soil foundations and the expected settlements (Baguelin et al. 1978). 
  • The pressure volume curve obtained from this test is used to compute the pressuremeter modulus E (Shear Modulus)
  • Pressuremeter tests are conducted in many types of soil, in boreholes drilled at different locations and to several depths. 
  • Samples of encountered soil are taken and tested in the laboratory. Numerical simulations of the pressuremeter tests are performed with Plaxis software. 
  • The results allow the determination of the elastic modulus of soil and the comparison to the corresponding pressuremeter modulus measured during the  in‐situ tests. 
  • For every type of soil, the variation of the ratio between both moduli is determined.
