Summary "The concept of effective stress and effective stress equation are fundamental for establishing the theory of soil mechanics and poromechanics. However, up till now, the physical meaning of effective stress has not been explained clearly, and the theoretical basis of effective stress equation has not been proposed. Researchers have not yet reached a common sense on the feasibility of the concept of effective stress and effective stress equation for unsaturated soils. Considering the effect of pore fluid pressure and the external forces excluding pore fluid pressure on the soil skeleton separately and defining the effective stress as the skeleton stress due to external forces, the effective stress equation can be derived and an explicit physical meaning of effective stress can be given. Based on the definition of skeleton, we consider the part of pore water which is bonded tightly with soil particles, bearing and transferring load together with the particles as a component of soil skeleton. Then, taking skeleton and pore fluid as research object respectively and considering the effects of the pore fluid pressure and the other external forces separately, the equilibrium differential equation of soil mechanics can be provided. Meanwhile, the effective stress equation and seepage equation can be derived. Finally, some possibly controversial problems are discussed to help the readers better understand the role of equilibrium equation and master the concept of effective stress. This book is a primary reading for the theory of soil mechanics in a new viewpoint. The audience of this book is senior undergraduates, graduate students, academics, and researchers major in soil mechanics, poromechanics, civil engineering, hydraulic engineering, traffic engineering, mining engineering and petroleum engineering."--Provided by publisher
