Applied Research Of High Vacuum Compacting Method In Foundation Treatment

As a result of planning and development needs,many coastal cities form a new development sites through artificial reclamation along the coastline the land from the sea.Most of the original coastline are the formation of surface fill,as a result of the thick of fill layer,as well as the source of differences in hydraulic fill sand,and fill technology of different soil,consolidation time's short,high water table,etc,more dredger fill soil is poor in region generally.It need to take effective treatment before it become the foundation of land for construction purposes.At present,there are so many methords of foundation treatment,in relation to the handling of large scope problem, these approaches have to deal with the high cost,long duration and difficult to carry out construction and other issues.In this paper,combined with blowing Metro Lingang filling approach,summarized a variety of foundation treatment at home and abroad,analysed its applicability,cost and use period,lay the foundation for a reasonable choice for the next stage.Through the use of finite element simulation method,a preliminary analysis for the Mechanism of reinforcement of high vacuum compacting method,a number of important design parameters had accessed;By high vacuum compacting method Treatment examples,we compared effect of high vacuum compacting method.The result indicated that dredger fill soil with high vacuum compacting method,its strenghth increased,high vacuum compacting method is fitnessfor the foundation treatment in this site.In the last,the technical requirements and process especially Mechanism of high vacuum compacting method had been discussed and analysed,through the test effect, the effectiveness of the method is obvious,with broad application prospects.
