Resumen: Este libro se basa en y sustancialmente actualiza Fredlund y publicación de Rahardjo, mecánica de suelos no saturados para los suelos, el estándar actual en el campo de los suelos no saturados. Se proporciona a los lectores con más cobertura completa del estado de la técnica de los suelos no saturados y refleja mejor la manera en que se resuelven los problemas prácticos insaturados de ingeniería de suelos. El mantenimiento de la física fundamental del comportamiento de suelos no saturados se presenta en el libro anterior, esta nueva publicación pone mayor énfasis en la importancia del "suelo-agua curva característica" en la solución de problemas prácticos de ingeniería, así como la cuantificación de las condiciones de contorno térmicas y de humedad en base en el uso de datos meteorológicos.
