GT-81-01  aA thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Engineering and Technology  aThesis (M.Eng.) - Asian Institute of Technology, 1982  aResults of laboratory studies on remoulade sand samples, from  Chao- Phraya River, Bangkok, Thailand, under anisotropic consolidation are discussed in this research.  The importance of initial void ratio and degree of saturation of  sand samples, formed during the laboratory investigations, in relation to their reproducibility is emphasized. Furthermore the implications of the effect of confining pressure on the consolidation behaviour of  sands vis-a-vis the determination of critical state parameter, ; ^, ·are  examined in some detail. A procedure to estimate ^ , is suggested. Data from p' = (a' + 2a') /3 =canst. and q· =(a' - a') = const. tests on anisotropically1   consolidated sand samples are used to evaluate the parameters needed in a semi-empirical stress-strain prediction model. Predictions by Modified Cam-Clay model and the semi-empirical approach are compared with experimental results obtained by conventional drained triaxial test, anisotropic consolidation and rebound test  and a special stress path depicting dq/dp = 1. 5 initially upto some stage followed by p' = canst. to failure.  It is emphasized that in the case of sands,. the stress strain behavior depends on both stress path and stress history, and a semi empirical approach to prediction of stress-strain behavior has much  to recommend itself. 10aSandxThailandxBangkokxTesting1 aYudhbir, eChairperson1 aOhta, Hideki, eExamination Committee1 aPrinzl, Frediric, eExamination Committee2 aAustralian Government, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
