摘　　要：为获取滹沱河地下水库入渗场设计所需的参数,在滹沱河河道开展了国内首次大型入渗试验,采用水量平衡原理求取了滹沱河河道的入渗能力。试验成果表明:动水条件下河道入渗能力明显优于静水条件,为增强入渗效果,建议未来建设地下水库进行调蓄时,采用动水条件进行设计;滹沱河河道入渗能力极强,动水条件下稳定入渗能力高达1.31m3(m2.d),为滹沱河地下水库入渗场工程设计提供了重要依据。In order to obtain the parameters required in designing the groundwater reservoir seepage field of the Hutuo River,a first domestic large-scale infiltration test was carried out in the Hutuohe River.Under the balance principle of water volume,the infiltration capacity of the Hutuo River was obtained.The results of the test show that the infiltration capacity of the channel under the hydrodynamic conditions is obviously superior to that under the hydrostatic conditions.To strengthen the infiltration effect,a design under the hydrodynamic conditions is suggested when constructing the underground reservoir for storage in the future.The infiltration capability of the Hutuo River is extremely strong.The steady infiltration capacity can reach 1.31m3/m2·d under the hydrodynamic conditions,which provides an important basis for the engineering design of groundwater reservoir seepage field for the Hutuo River.
