摘要
以滇中引水工程某深埋长隧洞为依托,在较深入了解研究区水文地质及工程地质条件的基础上,选取线路对地下水环境影响较大的区域进行示踪试验,通过试验不仅较清晰地查清了地下水运移通道,而且较为准确地查明了研究区地下分水岭,最终为线路的选择提供了合理、准确、可行的依据。
The application of tracer test in a deep-buried long tunnel project in the Central Yunnan water diversion pro-ject is introduced.Based on a comprehensive investigation of the hydrogeological and engineering geological conditions, the tracer test is carried out in the area that the groundwater environment is under great influence of the tunnel construc-tion.With the tracer test, the migration pathway and underground watershed of groundwater is clearly uncovered, which provides reasonable, accurate and reliable information for routine selection of the tunnel.
