Abstract

Infrastructural development effort on soft clay deposits that exhibit excessively low bearing capacity and potential for large settlements poses a challenge for geotechnical engineers. An adequate ground improvement program to achieve proper consolidation is thus a prerequisite for both long- and short-term stability. Pre-construction consolidation using surcharge load alone not only takes too long but also practically quite cumbersome and costly to achieve 90% consolidation. A surcharge preloading along with an arrangement of vertical drains when combined with vacuum pressure makes an attractive ground improvement alternative. This reduces the cost of stabilization and increases the effectiveness of the combined system. The provision of negative pressure in the vertical drains intensifies radial flow of porewater that expedites consolidation. This paper discusses nuances of this system and identifies factors to improve its effectiveness.
