Methodology for Foundations on Expansive Clays

Recent research into the behavior of expansive clays has led to rational procedures for quantifying swell and skrinkage and differential movements in expensive subgrades. These procedures, used in conjuntion with modern numerical techniques for analyzing the static interaction of foundations and soils, have permitted the development of rational foundation design procedures that can be employed in a design office. This paper surveys recent advances in these areas and summarizes the salient features of some of the more prominent studies.

Engineering problems associated with expansive clays from Romania

Engineering problems associated with expansive clay formations, which have a large swelling and shrinking potential, exist in different regions of Romania. In the general framework of the study of the behaviour of expansive clays, the present paper describes some particular aspects connected with the swelling and shrinkage processes and their engineering effects in Romania. The differences between swelling potential relationships, obtained by two different methods are presented and discussed. Swelling pressure tests were accomplished using the available standard techniques, as well as a specially developed cell pressure equipment. Attention is drawn to the stages of the shrinkage process as related to soil structure. It was found that, in a general case, there are three distinctṡtages: initial, normal and residual shrinkage. Laboratory investigations have shown that in soils with an anisotropic structure, the directional variation of shrinkage strains is elliptical in shape, with the maximum shrinkage normal to particle orientation. The engineering aspects of the results are discussed.
