WebFeb 1, 2012 · Modulus of Subgrade Reaction, ks. The CBR value of the clayey sand soil describe in figure 3 gives CBR value equal to 5.5%. By means of the developed correlation, if the Poisson’s ratio of the soil is 0.4, it gives the modulus of elasticity, E = 751 CBR (kPa) as in Figure 6. Thus the value of E = 4751.01 kPa. WebCorrelation relationships of dynamic (Evd) and static (Ms) soil modulus are as follows: • Granular soils – Evd ≤ 30 Mpa – Ms = 1,75 (Evd – 10) • Cohesive soils – Evd ≤ 30 Mpa – Ms = 1,16 Evd. – Evd > 30 Mpa – Ms = 1,42 (Evd – 30) + 35. The measurement process is completely digitized. On one location it is possible to ...
