Abstract: The Asaoka method has often been used to predict the post-construction settlement in geotechnical engineering and the consolidation coefficient can be calculated with the quantitative expression of consolidation coefficient Cv versus the slopeβ1 of the Si-Si+1 straight line in the Asaoka’s method based on the observed settlement data. However, it has been reported that the back-analyzed consolidation coefficients with the Asaoka’s method are not consistent with the in-situ one. This study investigated this discrepancy, and propsoed a new method for calculating the consolidation coefficient based on one-dimensional Terzaghi’s consolidation theory. The back-analyzed consolidation coefficients with the new expression are quite consistent with the in-situ one.

Key words: Asaoka method, Terzaghi consolidation theory, consolidation coefficient, back analysis, settlement data
