Approximate but accurate, simple invertible equations for the consolidation curves under triangular excess pore-water pressures are developed. These approximations can be used to calculate the degree of consolidation corresponding to a specified time factor (explicit) or the time factor corresponding to a specified degree of consolidation (implicit). Explicit equations are also developed for estimating the consolidation coefficient and final settlement, from two settlement readings, using the proposed approximations.
