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.
