摘要
采用一维垂直积水入渗试验,研究晋陕蒙能源区不同构型土体的水分入渗特性。结果表明:不同构型土体的入渗能力差异明显,表现为风沙土、黄土、砒砂岩的入渗能力依次降低,风沙土和黄土中采用混合添加和分层添加砒砂岩的方式均可以延长入渗时间并能降低入渗速率;在控制较高容重的条件下,含有料姜石和煤矸石的土体入渗能力低;层状结构土体的入渗能力低于均质土壤;采用线性函数可以很好地描述不同构型土体累积入渗量与湿润锋推进距离之间的关系;与Philip模型相比,Kostiakov入渗模型可以更好地拟合不同构型土体的入渗过程。
The soil infiltration characteristic is one of the most important soil physical properties.The structure and texture of the configuration soils in Shanxi,Shaanxi and Inner Mongolia energy region area are quite complex and results in different infiltration properties.In this study,the infiltration characteristics of different configuration soil were analyzed by one-dimensional vertical infiltration experiment.The results showed that soil infiltration characteristics were strong influenced by soil configuration,and the infiltration capacity decreased as aeolian sandy soil,loess soil and soft rock.The mixed adding and layered adding soft rock to aeolian sandy soil and loess soil both could extend infiltration time and reduce infiltration rate.The infiltration process of soil containing calcites and gangue was inhibited in the high bulk density condition.Layered structure soil had a lower infiltration capacity than homogeneous soil.The relationship between cumulative infiltration and wetting front advancing distance could be well expressed as a linear function model.Kostiakov infiltration model could better fit the infiltration process with different configurations(R~2>0.93) than Philip model.These results provide experimental evidence for soil water movement process and technical support for the reconstruction and reclamation of mining soils in Shanxi,Shaanxi and Inner Mongolia energy region area.
