The optimization analysis of drain spacing in soft soil improvement

Abstract

     This paper presents the calculation of soft soil improvement by probabilistic-based method, forcusing on the optimal determination of drain spacing. The case study is seltected for the soft soil improvemet work at Ca Mau Gas Processing Plant and compare with the conventional approach. The result shows the optimal drain spacing determinated by probabilistic-based approach is 1,1m whereas that of the conventional approach is 1,2m.
