The relationship curves of Young’s modulus changing with temperature under different water contents, dry densities, and confining pressures. (a) = 1.4 g/cm³, = 5%. (b) = 1.4 g/cm³, = 5%. (c) = 1.4 g/cm³, = 5%. (d) = 1.6 g/cm³, = 5%. (e) = 1.6 g/cm³, = 15%. (f) = 1.6 g/cm³, = 25%. (g) = 1.8 g/cm³, = 5%. (h) = 1.8 g/cm³, = 15%. (i) = 1.8 g/cm³, = 25%.
