| 中文摘要:为了进一步确定里耶古镇防洪堤砂卵石地基的渗透特性，采用原位钻孔注水试验的方法对5个断面共15个孔段进行了测定。试验结果表明，该防洪堤地基的渗透系数普遍较大，同一断面不同位置渗透系数存在一定差异，其中：1+070断面前坡马道渗透系数是后坡马道的4倍；2+470断面前坡马道的渗透系数是轴线处的10倍。 |

| Abstract:In order to confirm the boulder foundation permeability of Liye embankment, the spot boring water injection was adopted to test permeability coefficient from fifteen hole segments in five sections. The test results show that the permeability coefficients of embankment foundation are generally big, and different in each spot on the same section. The permeability coefficient of front slope path of 1+070 section is four times that of back slope path, and the coefficient of front slope path of 1+470 section is ten times that on the axle. |
