摘 要：
基于均质土壤的非充分供水与充分供水入渗试验数据,分析了非充分与充分供水入渗过程之间的关系,建立了非充分与充分供水入渗Kostiakov三参数模型参数之间的关系。结果表明:非充分供水积水后入渗过程以充分供水入渗过程为渐近线;非充分与充分供水入渗参数α的比值m随着供水强度的增加而增大、随着黏粒含量的增加而增加、随着砂粒含量的增加而减小、随着土干密度的增加而增加、随着初始含水率的增加而减小,它们之间都较好地符合乘幂函数关系;非充分供水稳定入渗率等于同条件下的充分供水稳定入渗率;非充分供水入渗系数K1等于供水强度与稳定入渗率之差。

摘 要：
On the basis of the non-sufficient and sufficient water supplied infiltration test of homogenous soil,the infiltration processes for both non-sufficient and sufficient water supplies were analyzed;the correlations of Kostiakov three model parameters for the non-sufficient and sufficient water supplies were established.The result shows that the ponding infiltration process with non-sufficient water supply accords with asymptotic curve of infiltration process with sufficient water supply;the infiltration parameter ratio m increases as the three elements of water supply,namely,intensity,clay content of soil grain and soil bulk density augment,while the parameter ratio m decreases as the two elements of sand content,and moisture content,the steady infiltration rate of non-sufficient water supply equals to steady infiltration rate of sufficient water supply;the infiltration coefficient K1 of non-sufficient water supply equals to the value of the difference between water supplied intensity of water supply and steady infiltration rate.
