Article Citation - Scopus: 1A computer-controlled triaxial swelling test apparatus(2004) Bilir,M.E.; Müftüoǧlu,Y.V.; Sari,D.To avoid the problems encountered during and after the construction of engineering structures built within swelling rocks or soils, data related to swelling stresses and strains should be used in the design stage. For an effective design, it is important that the data used for this purpose should be derived from triaxial swelling tests. In this article, a re-designed and computer-controlled triaxial swelling test apparatus is introduced. Due to the limited amount of test equipment, the work associated with triaxial swelling tests has been rather limited and consequently a test standard has not been developed yet. The computer-controlled triaxial swelling test apparatus has made tedious swelling tests easier and thus it has provided better possibilities for the investigation of the triaxial swelling behavior of soils and rocks.Article Citation - WoS: 5Citation - Scopus: 7Clay Content Effects on Triaxial Swelling Characteristics of Clay-Bearing Samples(Sila Science, 2012) Bilir, M. Erdinc; Sari, Y. Dursun; Muftuoglu, Yadigar V.; Donmez, Senayi; Department of Civil EngineeringThere are some factors which have an important influence on the swelling characteristics of clay-bearing structures such as type of clay mineral, clay content, stress path, confinement, and scale effect. This paper includes a study of some of these factors of a reconstituted clay-bearing rock samples using a computer-controlled triaxial swelling test apparatus. According to the test results, almost the same swelling potential and stress are observed for the samples having the same density, diameter/height ratio, smectite content, and a confining pressure. On the other hand, the smectite content and confining pressure have a significant influence on the swelling behavior.
