基于示踪试验的岩溶管道及水力参数定量解析
Quantitative analysis of karst conduit and its hydraulic parameters based on tracer test
摘要
Abstract
To explore the application of tracer test in karst groundwater, the tracer test of the karst groundwater in the zone of Jiuzihai Swale - Ganze Spring in Lijiang River is taken as an example. According to the hydrological and geological conditions in the zone, the groundwater connectivity and flow field characteristics are analyzed, and the location of karst conduits are reck-oned. A quantitative analysis of break-through curve ( BTC) of the tracers is carried out by using Qtracer2 calculation model. The test results prove the existence of hydraulic connection in the zone of Jiuzihai Swale - Ganze Spring and other karst con-duits. The structural and hydraulic parameters of the karst conduits are worked out, which confirmed that the karst groundwater is in the state of turbulent flow at a low velocity. It can be concluded that Qtracer2 is applicable to the quantitative analysis of BTC of tracers.关键词
