|Title:||EFFECTIVE STRESS RANDOM FINITE ELEMENT ANALYSIS OF CEMENT-TREATED CLAY GROUND||Authors:||PAN YUTAO||Keywords:||cement-treated marine clay; spatial variability; random finite element method; tunnel||Issue Date:||11-Aug-2016||Citation:||PAN YUTAO (2016-08-11). EFFECTIVE STRESS RANDOM FINITE ELEMENT ANALYSIS OF CEMENT-TREATED CLAY GROUND. ScholarBank@NUS Repository.||Abstract:||This study dealt with the random behavior of cement-admixed soil. In this thesis, an advanced constitutive model for cement-admixed soil was firstly incorporated in finite element program. Then the numerical model was recalibrated and validated using cell test results. Parametric studies were carried out to see how the each parameter may impact the result. This model was randomized by relating model parameters to unconfined compressive strength. The randomized model was then used in random finite element analysis of axially loaded cement-treated single column, laterally loaded cement-treated layer and tunnel with improved surround. With the results from random finite element analysis, probability-based design guidelines are provided for each case.||URI:||http://scholarbank.nus.edu.sg/handle/10635/134435|
