真空联合堆载预压在沿海滩涂地基处理中的应用

The Application of Vacuum Combined Surcharge Preloading in Foundation Treatment of Coastal Beach

真空联合堆载预压软土地基处理方法被广泛应用于港口、公路、水利工程等领域,并取得良好效果。以莆田市秀屿区产业园配套工程软基处理为例,采用真空联合堆载预压施工工艺,包括铺设工作垫层、铺设砂垫层、插打塑料排水板、真空管网连接、铺设无纺土工布、埋设监测仪器等,有效解决了该区域软土地基处理问题。

Vacuum combined surcharge preloading soft soil foundation treatment method is widely used in port,highway,hydraulic engineering and other fields,and has achieved good results.Taking the soft foundation treatment of the supporting project of Xiuyu District Industrial Park in Putian City as an example,the vacuum combined surcharge preloading construction process is adopted,including laying working cushion,laying sand cushion,inserting plastic drainage board,vacuum pipe network connection,laying non-woven geotextile,embedding monitoring instruments,etc.,which effectively solves the problem of soft soil foundation treatment in this area.
