低位真空预压法吹填土软基加固技术的应用

Application of Low Vacuum Preloading on Dredger Fill Soft Foundation Consolidation

滩涂围垦成陆后首先要进行围垦区的回填,以抬高围垦区的地坪高程,在确定回填方案时,填料来源和地基处理方法等方面的问题应予以重点考虑。低位真空预压法加固吹填土软基技术具有施工工艺相对成熟、成本低、工期短、对周围环境影响小、后续用地方便等优点,对于工期要求较紧的吹填土软基来讲,是较为合适的加固处理方案。

After reclamation of tidal flat is made,the fenced area is backfilled firstly to elevate the level ground.As the backfilling option is decided,the problems such as the source of backfill material and foundation treatment way should be considered emphatically.The technology of low vacuum preloading on dredger fill soft foundation is the one of relatively mature with the low cost,short construction period and less impact on the surrounding environment and it is convenient to expropriate land in the future.The method is an appropriate choice to consolidate the dredger fill soft foundation in a shorter construction period.
