【摘要】 从高放废物处置安全角度而言,区域地壳稳定性问题是高放废物处置库场址选择时首先要考虑的必要条件。笔者从地形地貌特点、区域断裂活动性与历史地震记录和地震烈度、现代地壳形变、区域地球物理场特征、地壳速度结构与岩石圈弹性厚度、大地热流与地热异常等6个方面来讨论此问题。结果表明东天山区域地壳稳定。更多还原

【Abstract】 In the safety view of high-level radioactive waste disposal, regional crustal stability is the first requirement needs to consider during site selection. This problem is analyzed in the way of topography and geomorphology, regional faults activity, historical earthquake records and seismic intensity, modern crustal deformation, regional geophysical field, crustal velocity structure and effective thickness of lithosphere elastic, terrestrial heat flow and geothermal anomaly. The results show that the regional crust is stable in eastern Tianshan.更多还原
