摘要
基于长江河口地区沉积物的特点,分析了该区域天然沉积土的渗透性能,得出渗透系数显著偏低的结论。采用孔隙特征预测土的渗透系数的方法,成功预测了长江口北岸天然沉积土的渗透系数,预测得到的渗透系数高出室内渗透试验结果一个数量级以上。这一结果应用于通启高速公路建设,取得了良好的经济和社会效益,具有很高的参考价值。
Based on sedimentary properties of deposit in the Yangtze river delta, osmosis characteristic of soils deposited in the region is analyzed as the result of which the coefficient of permeability measured in the laboratory is gcnerally small. The coefficient of permeability of natural intermediate soils on the northern bank of the Yangtze river delta is successfully predicted by porous materials models. The results show that the coefficient of permeability predicted is 1 magnitude greater than that measured in the laboratory. The economic and the social benefits favorably obtained have important reference value in Nan Tong to Qi Dong highway.
