Correlations between Menard Pressuremeter Modulus and Shear wave velocity results for various type of Algerian soils
Correlations between Menard Pressuremeter Modulus and Shear wave velocity results for various type of Algerian soils
Soil deformation modulus is an important geotechnical parameter that characterizes the stiffness of soils. Menard Pressuremeter Test (MPT) is one geotechnical field test that analyzes the elasto-plastic soil behavior through its stress-strain curve results. MPT is a well-known expensive in-situ test that determines soil deformation modulus, known as Menard Pressuremeter Modulus (Em). On the other hand, Shear wave velocity (Vs) is a geophysical parameter that characterizes soil stiffness more reliably and less costly. This study proposes correlation between Em and Vs for sand, clay, marl, and all soils. Very few contributions have been made to investigate the relationship between Em and Vs. This study provides an extensive database collected from different sites in central Northern Algeria. A comparison study was conducted between the proposed correlations in this study and those presented in the literature based on normalized consistency ratio (CR) values, revealing a good accuracy of the developed proposed models.
