摘要:

通过现场调查,获得了研究区岩溶裂隙与溶洞的发育特征;根据此特征,提出了变流量连通试验方法,并与示踪连通试验方法结合,进行了岩溶缝洞系统连通试验,分别测试了观测点流量与水样电导率随时间的变化。结果表明:研究区的岩溶裂隙与溶洞较发育;变流量连通试验方法和示踪连通试验方法相结合,可以确定岩溶缝洞系统地下水系与流体流动途径,为合理开发岩溶区地下水资源与确保水利水电等工程安全提供科学依据。

Abstract:

Characteristics of typical karst fracture-cave media of a observed region were analysed by means of field investigation. A method of consecutive tests of a variable flow rate was posed according to the characteristics. Consecutive tests were performed by the method combined with a method of consecutive tests of a tracer. Changes of a flow rate and electrical conductivity of water samples with time were determined for observation points. Results show that karst fracture-cave of the region is developed and that groundwater systems and pathways of groundwater flow in the karst fracture-cave media can be determined by the two methods of consecutive tests. The results can provide scientific basis with groundwater resource exploitation and hydraulic & hydropower projects safety assessment in a karst region.

Key words: Karst fracture-cave system    Groundwater system    Pathways of groundwater flow    Engineering safety    Consecutive test of variable flow    Consecutive test of tracer.
