| Abstract: | The relationship between the deformation-modulus and the shear-modulus of pressuremeter test in sandy soils isanalysed in the paper. Two formulas of a=f(E_m/p_l) with continuous and gradual variation for the valued have been presented to calculate the k-coefficient of modulus-transformation. Fifteen points of MPT and PLT testing results and those of six MPT and CPT have also been presented for comparing the results of this method with Menard's a-E_m/p_l Table. |
