Summary
This paper presents a new power law for describing the dependency of elastic modulus on soil water content. Experimental data of either Young’s modulus from 11 different soils are used to examine the validity of the proposed power law. It is shown that the proposed power law can well represent the highly non-linear relation between elastic modulus and soil water content in silty and clayey soils.
