物探技术在花岗岩体处置库选址中的应用研究

Application of geophysical technology in granite mass disposal library

当前世界各国处置高放废物时采用了多种方案,当前公认的有效方案是深地质处置,也就是说,将“地质处置库”建造在地表下面500~1000 m的地质体中,发挥这一天然屏障的作用,加以工程屏障对高放废物永久隔离。但是在围岩中建设高放废物处置库时,需要从整体的角度出发对岩体地质构造所具备的特征进行研究,明确地质构造问题,这是处置库成败的重要因素,对此需要采用科学有效的方法勘查清楚,因此,着重研究物探技术在花岗岩体处置库选址中的应用。

At present,various countries in the world have adopted a variety of schemes for the disposal of high-level radioactive waste.At present,the recognized effective scheme is deep geological disposal,that is,the“geological disposal repository”is built in the geological body 500-1000 meters below the surface to play the role of this natural barrier.In addition,the engineering barrier can permanently isolate high-level radioactive waste,However,when the high-level radioactive waste repository is carried out in the surrounding rock,it is necessary to study the characteristics of the geological structure of the rock mass from an overall point of view and clarify the geological structure,which is an important factor for the success or failure of the repository.For this,it is necessary to use scientific and effective methods.This paper focuses on the application of geophysical technology in the site selection of granite disposal repository.
