地球物理勘探技术在地质处置库选址中的应用

简要介绍了我国高放废物地质处置库选址的发展趋势,说明深部断裂构造、岩体的空间形态以及局部不良地质体是当前处置库选址的主要地质问题,综合论述了高放废物处置库选址中采用的地球物理勘探技术,介绍了重磁勘探、地震勘探、电磁法勘探及地面γ能谱测量等地球物理勘探技术,并且以甘肃北山新场预选区岩体为例,说明地球物理勘探技术解决的主要地质问题以及存在的不足。结果表明,该技术在探测处置库预选区花岗岩深部地质构造特征方面具有明显的优势,为处置库场址的稳定性和完整性评价提供参考。

Application of Geophysical Exploration Technology in the Sitting of Geological Disposal Repository

This paper introduces the development situation of highlevel radioactive waste repository sit ting in China, and indicates that the main geological problems in site selection are deep geological struc tures, spatial form and local adversity of the pluton. By summarizing the geophysical methods which are used in highlevel radioactive waste repository sitting in Xinchang ptuton, such as gravity, magnetic, seismic, electromagnetic and spectrometer technology, the ability and deficiencies in solving the main ge ological problems was summarized and explained. Actual results of the detecting shew that geophysical techniques can provide an important reference in sitting the repository for highlevel radioactive waste dis posal.
