| 摘 要： | 根据土水势能原理,在试验、监测资料基础上,建立活塞武、扩散式两种入渗补给模型和单一入渗、单一蒸发及入渗蒸发三个子模型,与此相应地建立了积水模型法,表面通量法,毛细带上缘通量法和零通量面法的数学模型,描述入渗补给的时、空变化过程,计算降雨入渗补给量,从土水势能观点提出降雨入渗补给的物理机制,并在实际应用中得到了证实。

| Abstract: | According to the soil- water potential theory, based on the experimental and monitoring data, this paper has built several models for rainfall recharge to the unconfined aquifer, i. e. ,the piston model, the diffusion model, and three sub-models in which the single infiltration, single evaporation and infiltration-evaporation have been considered respectively, Several methods have been used to describe the variation of recharge in time and space and to calculate the water quantity recharged by rainfall, such as ,the impoundment simulation, the surface influx method, the upper bring influx method of the capillary zone, and the zone influx face method. A physical mechanism of infiltration-recharge has been proposed, based on the point of energy conservation, and it has been verified in practice. |
