Review of mehods of analysis for the use of vacuum preloading and vertical drains for soft clay improvement

摘要

The use of vertical drains with vacuum preloading for soft soil improvement has become a booming interest in recent years. In this paper, theoretical and practical developments of the utilization of vertical drain with vacuum preloading are currently reviewed. Geotechnical aspects of factors affecting the performance of vacuum consolidation and conversion procedure for multi-drain analysis are discussed based on the current state of the art. The salient aspects of selected case histories on soft clays and land reclamations are elucidated.
