沿海吹填淤泥质土交工标准的确定

Determination of the standard for coastal hydraulic filling silty soil

水力吹填淤泥质土上滩后再地基处理成为陆域形成的常规工艺,在沿海江苏、浙江地区有大量工程实例,但各个地区吹填淤泥质土的交工标准却不尽相同,其对工程质量有关键影响。结合温州某工程实例,从标高、平整度及土质3方面对吹填淤泥质土交工标准进行分析、确定,提出了"标高+重度"双控制的交工标准。

The reclamation and foundation treatment of hydraulic filling silty soil becomes a common process of land formation,there are a large number of engineering examples in coastal areas of Jiangsu and Zhejiang, but the standards for hydraulic filling silty soil are not the same, it忆s a key effect to the project quality. Combining with an engineering example of Wenzhou, from 3aspects of the elevation, flatness and soil to analyze and determine the standards for hydraulic filling silty soil, we put forward the standard of the "elevation + density" double control.
