摘要
从国外经验和国内前期研究成果来看,在中国粘土岩是高放废物地质处置库建设中重要的候选围岩之一。对陇东地区进行了地质调查,介绍了该地区的区域构造和区域地质特征,并重点对该地区的粘土岩的基本物理性能和渗透性能进行了研究。通过自行设计制作的渗透装置,测定了粘土岩的渗透系数。结果表明,该地区粘土岩的渗透性极低,渗透系数约为10-11 m/s,为高放废物处置库围岩选择提供了重要参考。
It is key point to choose the host rock to dispose of high-level radioactive waste for each country which has nuclear operation to undertake a systematic research about host rock.From the forging experiences and domestic pre-research,in China,claystone is one of the important alternative host rocks to dispose of HLW.The article is to present a description of geological investigation,regional structure and regional geological features of Longdong are.The result showed that osmosis of claystone is very low,and permeable performance is about 10-11 m/s.It provides important reference for choosing host rock of disposing of high-level radioactive waste.
