随着海峡西岸经济区、海上丝绸之路核心区建设,福建地区围海、围垦造地迎来新一轮发展。福建地区海相淤泥土具有显著的地域特点,即含水率高达60%以上,局部可达80%,普遍高于我国其他沿海地区;沿海滩涂地海产养殖业发达,土壤生物质富营养化对淤泥土性状的影响十分显著,因此,在该地区对深厚超软地基类进行真空联合堆载预压处理时,针对性经验缺乏。本文通过福建地区大面积深厚超软地区填海工程实例分析,综合考虑技术和经济、时间和效益等因素,对深厚超软地基真空预压处理,提出工艺技术参数建设性建议。
With the construction of the core area of the economic zone on the west side of the Taiwan Straits and the maritime Silk Road, the sea reclamation and land reclamation in the Fujian area usher in a new round of development. The marine silt in Fujian area has significant regional characteristics, that is, the moisture content is as high as 60% or more, and the local up to 80%, which is generally higher than other coastal areas in China. Developed aquaculture along coastal beaches and eutrophication of soil biomass The influence of soil properties is very significant. Therefore, lack of pertinent experience in the vacuum preloading of deep super soft ground in this area. Based on the analysis of the reclamation project in a large area of deep and super soft area in Fujian Province, this paper puts forward constructive suggestions on the technical parameters of the deep ultra-soft ground under the condition of vacuum preloading by comprehensively considering such factors as technology, economy, time and benefit.
