Abstract: This paper presents a case history of monitoring the performance of high fill embankments in an airport construction in southwest China. A simplified settlement estimation of the soils underneath the high fill embankment is also proposed. Based on the normally consolidated, underconsolidated and overconsolidated status of original soils, the compression modulus and the settlement of soils under three states are determined.  The compression modulus Es and the empirical coefficient ψs are also back analyzed by using the monitored data.
