Assessment of recent methods for determination of soil final settlement using field data

Abstract. The problem of soil consolidation was first studied by Terzaghi who formulated the well-known one-dimensional consolidation theory. However, this widely used method was found to provide poorly accurate estimations, since Terzaghi considered the assumption of constant permeability and consolidation coefficient. The poor accuracy is also due to the low resemblance between laboratory results and field actual measurements. In order to overcome this issue, many researchers proposed new approaches to estimate and predict soil settlement more accurately. Among these approaches, field-based methods are particularly promising. For instance, the Asaoka method (1978), Sridharan (1987) method, Tan (1995) method, Chunlin’s method (2014), and recent methods of Guo et al. (2017, 2018b) and Guo et al. 2018(a,). This paper aims to assess and discuss the results of some recent methods using a field consolidation monitoring data set.
