<p><span style="color: #333333; font-family: 'Open Sans', sans-serif; font-size: 15px;">Chapter 5 - Shear Strength of Unsaturated Soils </span><span style="color: #333333; font-family: 'Open Sans', sans-serif; font-size: 15px;">addresses the determination of shear strength of unsaturated soils. The latter is described by two independent state variables among which soil suction contributes to the cohesive component of soil. Measurement of shear strength of unsaturated soils is conducted by the conventional shear box and triaxial equipment needing modifications to allow air-entry in tested specimens. Using the shear strength parameters of unsaturated soil, current soil mechanics applications: e.g. earth pressures, bearing capacity and slope stability of foundations are formulated.</span></p>
