APPLICATION OF VACUUM PRELOADING IN GRAVITY PLATFORM DESIGN

【摘要】:正 Vacuum preloading has been widely used in harbour engineering to accelerate the consolidation of soft clay. The mechanism of the method is dicussed in this paper by presenting a consolidation model under the action of negative pressure. A scheme of using vacuum preloading in designing a gravity platform is proposed to strengthen the soft clay layer on which the platform will be placed. Details of a drainage system are discribed and the functions of the system are also discussed.
