该文在三峡风化砂侧限压缩渗透试验的基础上 ,分析了风化砂的渗透系数随密度的变化规律。通过试验结果的回归分析 ,导出了渗透系数与应力及干容重之间的关系式。这些结论对于堰体的渗透分析有一定的实际应用价值
Based on the limited compression infiltration test of weathered sand in Three Gorges Project, the variation law of permeability coefficient of weathered sand with density is analyzed. Through the regression analysis of test results, the relationship between permeability coefficient and stress and dry bulk density is derived. These conclusions have certain practical application value for infiltration analysis of weir body
