摘要
通过对秦岭特长铁路隧道区不同天然水体氢、氧稳定同位素及放射性同位素初步研究,得出隧道区存在浅部风化裂隙水和下部构造裂隙水两个地下水流系统的结论。各系统地下水补、径、排条件不尽相同,下部构造裂隙水既有40年前的“老水”,又有新近渗入水与“老水”的混合水;浅部风化裂隙水主要为新近入渗水及与“老水”的混合水。隧道工程影响范围内的地下深处未发现初生水或封存水。
On the basis of the preliminary study on stable and radioactive isotope of oxyhydrogen in different natural water bodies at Qinling tunnel, it comes to the conclusion that two groundwater systems are existed at Qinling tunnel, i. e. the fissure water in shallow weathered zone and the water in lower level tectonic fracture zone. In different systems, the recharge, runoff and drainage conditions of groundwater are not quite identical. There exists not only the 'old water' aged more than 40 years, but also the water mixed with recent infiltration water at lower level tectonic fracture zone. In shallow weathered zone, the main part of fissure water is recently infiltrated water and the water mixed with 'old water'. Neither juvenile water nor sedimentary water is found at the deep level of the influenced area by tunnel project.
