LABORATORY AND NUMERICAL INVESTIGATION OF THE PERFORMANCE OF BENDER ELEMENTS IN CEMENT-TREATED CLAY. ScholarBank@NUS Repository. | Abstract: | Bender element testing is commonly used to obtain the small-strain shear modulus of a soil from shear wave velocity measurements. The current study investigates the applicability of bender element testing to cement-treated clay of high stiffness. The interaction between the bender element and soil sample was examined by laboratory investigation and finite element modelling to identify key factors that influence shear wave propagation within the soil sample. The results indicate that the sample size, aspect ratio, and input frequency directly affects the accuracy of shear wave velocity measurements. Furthermore, the resonant behaviour of the bender element embedded in a soil sample was investigated using the developed finite element model. Finally, the application of bender elements to small-scale 1-g model testing on cement-treated clay was explored as a means of non-destructive detection of voids or untreated zones in a cement-treated clay ground used for quality control and assessment ground improvement. | URI: | https://scholarbank.nus.edu.sg/handle/10635/190508 |
