Abstract
This paper presents the results of tests carried out around 1970 on loess from the southeast of England. In these tests, air-dry samples were flooded with different fluids whilst under load in order to investigate the influence of the clay fraction within the soils on the collapse process. The fluids used were selected on the basis of their postulated influence on clays. Not only did the various fluids influence the amount of collapse that occurred on flooding but also the compressibility of the soil structure for subsequent load application post-flooding. The results indicate that the collapse phenomenon occurs through micro-shearing at the intergranular contacts and is influenced by the clay component in the soils. An explanation of the phenomenon is presented in terms of a modified effective stress equation.
