地下水人工回灌淤积的室内试验研究

THE INDOOR EXPERIMENTAL RESEARCH OF DEPOSITION IN ARTIFICIAL RECHARGE OF GROUNDWATER

在进行地下水人工回灌过程中常常产生淤积问题,而淤积与回灌水源的浊度、回灌水层厚度、回灌地点的颗粒级配有关。为了研究淤积的影响因素,本文利用室内试验对其影响因素进行的分析表明,影响淤积的主要因素是浊度,其次是水层厚度。在此基础上,建立了淤积高度与影响因素的多元统计方程。

Deposition often occurs in the process of artificial recharge of groundwater. This is related to the turbidity of recharge water seurce , thickness of recharge layer and grade of grain in recharge site. In order to study the influential factors of deposition, we carried out an indoor experiment. The resuls show that the major factors are turbidity and thickness of recharge water layer. Furthermore, the authors set up the multi-variable statistical equation involving the height of deposition and the influential factors.
