【摘要】：為探究巖溶含水系統(tǒng)中裂隙-管道介質間不同補給方式下水流交換情況,在實驗室內(nèi)借助高精度攝像儀和有色示蹤劑對其進行可視化觀測。設計多組試驗對單獨補給裂隙、共同補給、裂隙和落水洞分開同時補給三種補給方式下水流交換情況進行探討,從而定性地分析水流交換情況。試驗結果表明:落水洞對裂隙水擴散的影響隨裂隙距離落水洞的距離增大而減小;相較于共同補給情況,單獨補給裂隙情況下落水洞對裂隙水擴散影響較大;在分開同時補給情況下裂隙與落水洞補給水量相同時,僅呈現(xiàn)裂隙對落水洞的單向補給。
[Abstract]:In order to investigate the water flow exchange between fissure and pipeline media in karst water-bearing system, a high precision camera and colored tracer were used to visualize the flow in the laboratory.In order to qualitatively analyze the water flow exchange under the three recharge modes of single recharge joint recharge fissure and falling tunnel separately and simultaneously recharge the water flow is studied in the design of multi-group tests in order to qualitatively analyze the water flow exchange.The experimental results show that the influence of falling tunnel on the diffusion of fissure water decreases with the increase of the distance from the fissure to the water hole, and the influence of falling tunnel on the diffusion of fissure water is greater than that of common recharge in the case of single recharge of fissure.In the case of separate recharge at the same time, only the one-way recharge of the fissure to the falling tunnel is presented when the recharge quantity of the fissure and the falling tunnel is the same.
