Instead of fixating on formulae, Soil Mechanics: Concepts and Applications, Third Edition
focuses on the fundamentals. This book describes the mechanical behaviour of soils as it …

An unsaturated soil is a state of the soil. All soils can be partially saturated with water.
Therefore, constitutive models for soils should ideally represent the soil behaviour over …

We propose that the recently conceptualized suction stress characteristic curve represents
the effective stress for the shear strength behavior of unsaturated soil. Mechanically, suction …

Unsaturated soil mechanics has rapidly become a part of geotechnical engineering practice
as a result of solutions that have emerged to a number of key problems (or challenges). The …

Experimental data from different testing methodologies on different compacted clayey soils,
with dominant bimodal pore size distribution, are presented and analysed, to provide a …

The concept of the suction stress characteristic curve (SSCC) for unsaturated soil is
presented. Particle-scale equilibrium analyses are employed to distinguish three types of …

Consideration of the different roles of pore air pressure, pore water pressure within bulk
water and pore water pressure within meniscus water suggests that the degree of saturation …

Current alternative choices of stress state variables in unsaturated soils are described and
compared, with a special focus on the use of an effective stress. Experimental data on …

The range of problems that geotechnical engineers must face is increasing in complexity
and scope. Often, complexity arises from the interaction between the soil and the …

The effective stress principle, conventionally applied in saturated soils, is reviewed for
constitutive modelling purposes. The assumptions for the applicability of Terzaghi's single …
