【摘要】 在野外水文地质调查基础上,开展了北山地区地下水系统特征、岩体渗透性能、地下水动态、水文地球化学、地下水同位素、地下水CFC以及地下水流场模拟等综合性水文地质研究。依据大量资料的科学分析,综合论述了研究区水文地质条件、地下水循环交替特征、地下水化学特征和动力学特征,并对北山地区作为高放废物处置库场址预选区的适宜性进行了评价。通过这些工作,不仅为我国高放废物地质处置库选址建立了系统的水文地质研究和评价方法,也为在该区筛选最适宜的高放废物处置库场址提供了重要的水文地质依据。更多还原

【Abstract】 On the basis of large scale field hydrogeological investigation, synthetic hydrogeological studies related to groundwater system characteristics, permeability of rock bodies, groundwater dynamic, hydrogeochemistry, isotopic hydrology, CFC’s of groundwater and groundwater flow field simulation were carried out for Beishan area, Gansu province. According to analysis on a large amount of hydrogeological data, the characteristics of groundwater circulation, groundwater hydrodynamics and hydrgeochemistry were described and the suitability of Beishan area as the potential area of high-level radioactive waste disposal was evaluated in the paper. Through this study, the hydrogeological study and evaluation methods in the siting of China ’s high level radioactive waste repository were set up. Furthermore, the important hydrogeological scientific evidence was provided for optimal site filtration of China’s high-level radioactive waste repository in Beishan area.更多还原
