Basis for the Consideration of Deformations due to Swelling

  • Walter Wittke
Chapter

Abstract

The penetration of water into certain sedimentary rocks leads to deformations as a result of swelling, this in turn being a consequence of chemical transformations or the physical adsorption of water by various clay minerals. These changes of volume are a function of stress and are superposed onto the elastic and viscoplastic deformations handled in Chapter 3, they cannot, however, be described in terms of the relationships derived in that chapter. Volume changes due to swelling, especially in, tunnel engineering, have led to serious damage in the past and this has provided the impetus for a series of fundamental investigations [4.1 – 4.3, 4.8].
