沿海潮差带粘性土地基,一般都是新近沉积的淤泥质粘土或淤泥,采用一般的围埝结构和施工方法,造价高、工期长,往往满足不了建设的需要。通过工程实例分析,提出了国内首先应用在流泥和浮泥的地基上,以潮差带真空预压加固法处理地基基础联合模袋固化土构成的围埝结构型式,相对其它围埝结构,这种新型结构型式工期短、造价低、施工工艺简单,能够保证工程质量。

Clay foundation with coastal tide range are generally newly deposited silty clay or silt,the common cofferdam structure and construction methods are high cost,long duration,and often unable to meet the needs of construction.Through analysis of project examples,this paper proposes the cofferdam structure,which was constituted by vacuum preloading method treatment foundation at coastal tide range,and combined with geotextile solidified soil,was first used in China for the foundation of flow mud and float sludge.Comparing with other cofferdam structures,this new structure is short in construction duration and low cost and the construction technology is relatively simple to ensure construction quality.
