潜水人工补给新方法

为了有效增加地下水资源可利用量,对潜水人工补给方法进行了创新。在分析地下滴灌技术、地下水人工补给方法的基础上,提出建设地下暗管式人工补给系统的具体思路,给出了稳定下渗状态下系统补给量的估算方法;并基于台兰河地下水库实际水文地质条件,计算了修建10km入渗暗管时系统的补给量。对建设地下暗管式人工补给系统的优缺点、适用条件及其各构筑物的结构设计原理进行了初步探讨。结果表明:地下暗管式人工补给系统可以最大程度地减少表层土壤的含水量及陆面蒸发损失;同时,10km入渗暗管仅从当年11月至翌年2月入渗水量便可达约220万m3,这可为地下水库人工补给提供有力保障。总之,地下暗管式人工补给系统是水资源高效利用的一种创新模式,对实现水资源合理配置,保障地区用水安全具有重要意义。

New Method for Artificial Recharge of Phreatic Groundwater

In order to effectively increase the amount of available groundwater resources ,a method of artificial recharge is innovated .Based on the analysis of subsurface drip irrigation techniques and the method for artificial recharge of groundwater , the constructive idea of underground pipe artificial recharge system was put forward .The groundwater reservoir in Tailan River was taken as a case to calculate the quantity of artificial recharge . T he advantages ,disadvantages ,and the main points of structure design of the underground pipe artificial recharge system were discussed .The results show that the new method can reduce the soil moisture of the surface soil and land evaporation effectively .At the same time ,the case study in Tailan groundwater reservoir shows that the amount of infiltrating water can reach about two million and two hundred thousand cube through a 10 kms subsurface pipe , which provides a powerful guarantee for artificial recharge of groundwater reservoir .In general ,the system is a new method for effective utilization of water resources ,it is of vast importance to the security of water use and the achievement of reasonable allocation of water resources .
