In this context, the long-term deformation behavior of Boom clay is of crucial importance in the performance assessment of the whole storage system. In this study, low and high pressure oedometer tests are carried out; the e-log sigma(v)' (void ratio-logarithm of vertical effective stress) and e-log t (void ratio-logarithm of time) curves obtained are used to determine the compression index C-c*, swelling index C-s* and secondary deformation coefficient C-alpha during both loading and unloading. The relationship between C-alpha and the effective stress ratio (sigma(v)'/sigma(c)'.c, vertical effective stress to pre-consolidation stress) is analyzed, and it is observed that C-alpha increases linearly with log sigma(v)'/sigma(c)'. Examination of the ratio of C-alpha/C-c* for various soils shows that the secondary deformation behavior of Boom clay is similar to that of shale and mudstone. The relation between C-alpha and C-c* is linear; but the relation between C-alpha and C-s* is bi-linear. The bi-linearity observed is related to two different mechanisms: the mechanically dominated rebounding and the physico-chemically dominated swelling.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"An experimental study on the secondary deformation of Boom clay","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Boom clay; oedometer test; Secondary deformation behavior; Mechanicallydominated rebounding; Physico-chemically dominated swelling","OtherDescriptors":null,"Notes":null,"AnaPub":2012,"MonPub":null,"DateUpdate":"2016-06-15","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000304291100004","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.clay.2012.02.001"},"refs":null,"anarec":{"AnaID":257489,"PubliDate":2012,"Pagination":"19-25","XtraPublOfAnaID":null,"ISBN":null,"Volume":"59-60","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":258828,"SerRR":"Applied Clay Science.
