On the assumption that the product ofvolume thermal expansivity and bulk modulus based on the thermodynamic approximation theory, a new equation is presented for volume thermal expansioncoefficient.
Theses parameters include compression index, expansion index, coefficientof secondary consolidation and initial coefficient of re consolidation volume compressibility, et al.
