Interpretations of measured and back-anlaysed results of centrifuge tests

Abstract

This chapter reports and compares measured results of two centrifuge tests (as described in Chap. 6) and back-analysed results of the centrifuge tests by three-dimensional coupled-consolidation analyses (as described in Chap. 7). The physical and numerical investigation aim at studying (a) the initiation and failure mechanism of base instability due to hydraulic uplift; (b) base stabilisation effect of ‘anti-uplift piles’ installed inside excavation. Moreover, numerical parametric study was carried out to investigate effect of embedment depth of ‘anti-uplift piles’ on effectiveness of base stabilisation.
