Abstract

This study analyzed characteristics of soft ground consolidation according to depths of vertical drain. As the result, when the depth ratio of vertical drains (L/D) were 0.5, 0.7, and 1.0, consolidation characteristics were similar up to 70% in consolidation degree under one-dimensional drain condition. However, above this degree, consolidation speed became slower as L/D became smaller. Two-dimensional drain condition also showed a similar tendency, but when L/D was 1.0, the consolidation speed was relatively higher.
