The paper reports some experimental studies carried out on hydraulic fills, in an attempt to understand their settlement pattern which is quite different to what has been reported for clays and sands. The immediate settlement in hydraulic fills is about 60% of the total settlement, and the remaining 40% of the time-dependent settlement includes primary and secondary compression components which are difficult to separate. The inter-relationship among permeability, effective stress and settlement is also investigated. It appears that the coefficient of secondary compression Cα increases with the applied loading but is independent of time. Settlement (s) is a bilinear function of logarithm of time, taking the form of s = s0 + a log t, where s0 is approximately the immediate settlement.
