为探究裂隙-管道介质调蓄功能的影响机制,提高岩溶水资源开发利用效率,通过建立裂隙-管道介质物理模型分析了不同补给方式下模型的调蓄系数与补给强度之间的关系。分别设计单独补给落水洞、单独补给裂隙、共同补给裂隙与落水洞三种补给方式的试验,在不同的补给强度下监测泉口流量过程。试验结果表明,随着补给强度的增大,调蓄系数逐渐增大,单独补给裂隙情景下,调蓄系数与补给强度呈指数型增加趋势;单独补给落水洞、共同补给裂隙与落水洞时,调蓄系数与补给强度呈线性增加趋势。当补给达到一定强度后,单独补给裂隙时,调蓄系数不随补给强度变化,而其他两种补给方式下,调蓄系数持续增大。
In order to explore the influence mechanism of fissure-pipe media regulation and storage function and improve the efficiency of development and utilization of karst water resources, the relationship between the storage coefficient and the supply strength of the model under different supply modes was analyzed through the establishment of fissure-pipe media physical model. We separately design experiment of feeding three kinds of replenishment ways, such as single supply of falling water hole, single supply of fissure, common supply of fissure and sinkhole, and the monitoring of outlet flow under different supply intensity. The experimental results show that with the increase of recharge intensity, the storage coefficient increases gradually, and the storage coefficient and recharge intensity increase exponentially with the supply of fissures alone. When the recharge channels are supplied separately and the fissures and sink holes co-replenish, Storage coefficient and supply intensity showed a linear increase trend. When the supply reaches a certain intensity, when the fissure is supplied separately, the storage coefficient does not change with the supply intensity, while the other two kinds of supply mode, the storage coefficient continues to increase.
