川北—陕南地区高放废物处置库场地的预选

PRESELECTION OF GEOLOGICAL DISPOSAL RESERVOIR SITES OF HIGH-LEVEL WASTE IN NORTHERN SICHUAN-SOUTHERN SHANXI REGIONS

本文论述了川北—陕南地区的岩性、构造特征及新构造运动的活动特点,并根据这一特点及地震危险带的分布状况,在本区圈出了4片稳定区。又依据围岩成分、水文工程地质及自然经济地理条件,在稳定区内圈出了4片处置库场地预选区,并对其进行了可行性研究。文中论证了花岗岩是处置库的有利围岩,并根据几年的工作体会,阐述了库址预选的原则。

This paper states the petrography, the features of structure and neotectonics in northern sichuan and southern shanxi regions. Four stable regions are divided within the region on the basis of this characteristic and the distributions of earthquake risk zoning. Then according to contents of wall rocks, hydrogeology, engineering geology and physical and economic geography of the stable regions, four preselection regions of disposal reservoir sites are determined, at the same time, some feasible studies have been done on the sites. The paper also proved that granite is the advantageous wall-rock of the disposal reservoir, and the preselection principle of the reservoir is stated in terms of the working experience of several years.
