Abstract
The surcharge technique is one of highly effective and economical means for accelerating consolidation and reducing post-construction settlement. This paper is concerned with one-dimensional consolidation analysis taking account of the removal of surcharge. A series of laboratory consolidation tests are made on two normally consolidated organic soils to confirm secondary compression behaviors after the removal of surcharge. Based on the laboratory investigation, a method of estimating the amount of secondary compression is proposed empirically for practical use. One-dimensional consolidation analysis is described for predicting the consolidation-time curve before and after the removal of surcharge. Satisfactory agreement can be obtained between the computed results and oedometer observations.
