桥梁工程地基土体渗透特性研究——以江阴长江大桥北锚碇为例

Soil Permeability Characteristics of Bridge Foundation-An Example of North Anchor of Jiangyin Yangtze River Bridge

江阴长江大桥北锚碇地基孔隙水与长江水位关系密切。地基土渗透参数反演计算结果为,在北锚碇施工技术应用后,第四土层渗透参数能够合理下降23%。反合理性检验表明,计算所得到的土体渗透参数是唯一且合理的。

There's close relationship between the foundation pore water of north anchor of Jiangyin Yangtze River Bridge and Yangtze River water level.Soil permeation parameters inversion result is that after the application of construction technology in north anchor,the fourth soil infiltration parameters can reasonably fall 23%,which is proved by the anti-rationality test being unique and reasonable.
