A METHOD TO DETERMINE THE SWELLING OF A SOIL WITH FINAL SUCTION MEASURES DIFFERENT FROM ZERO

METODOS PARA DETERMINAR EL HINCHAMIENTO DE UN SUELO CON VALORES DE LA SUCCION FINAL DISTINTOS DE CERO

The majority of methods utilized to determine the swelling of a soil consist of flooding or suction of the sample under certain load conditions. Such procedures yield conservative results in the determination of the total swelling. In this study it is supposed that final suction value is known. Some mainly approximative methods based on semiempiric ratios between suction variation and volume increment are reviewed, as are Richard's method, controlled suction oedometer and other methods based on the suction-humidity relationship. Although it is generally thought that controlled suction oedometer is the best method to measure swelling, the linear character of roads and airports in which there are frequently variations in soil characteristics, make it convenient to use approximative methods.
