我国高放废物处置库甘肃北山预选区地壳稳定性研究
|
摘要
在总结国内外已有的经验的基础上,从下列几方面较深入地探讨了北山地区的地壳稳定性问题:区域大地构造特征及其演化历史,区域地球物理场特征及地壳结构分区,区域深断裂特征,区域地震活动性,区域新构造运动特征,区域现代构造应力场及其计算机模拟,TM遥感影像地质解译在地壳稳定性研究中的应用,以及区域地壳稳定性评价。研究结果表明,研究区可划分成八个不同的稳定性区域。其中,北山稳定区条件最好,其地壳稳定性符合国际原子能机构1994年安全指南111-G-4.1对高放废物处置库场地预选的要求,可以作为处置库预选区,开展进一步的场址筛选和场址特性评价等工作。
Based on international experiences of site selection, the crust stability of the Beishan area is studied. The researched problems are regional tectonic structure and its evolution, regional geophysical field, crust structure, regional deep-rooted faults, regional seismological activity, regional neo-tectonics, regional modern stress Field and its numerical simulation, geological interpretation of TM satellite images and its application in the study of crust stability. The research in the past years indicates that the western part of Gansu province (the studied area) can be divided into 8 parts with different crust stability. Among those parts, the Beishan area possesses the best conditions, its crust stability accords with the demands on candidate site for HLW repositories, which are described in the International Atomic Energy Agency's Safety Series No. 111-G-4.1 Guidelines.
