Discussion of “Unified Effective Stress Equation for Soil” by Chao Zhang and Ning Lu

Abstract

The authors' idea of including the sorptive potential in the suction stress is undoubtedly pioneering and new; however, as much as it introduces and highlights the potential importance and implications of the adsorptive potential in geotechnical practice, it exposes the geotechnical community to new unanswered questions. The discussers would like to elaborate on some of these issues.
