摘要
地下核试验瞬间释放的巨大能量引起地壳能量的连锁反应,产生诱发地震等地球物理现象。本文对20世纪前苏联与美国进行的地下核试验数据进行整理与归纳,给出地下核爆炸试验诱发工程地震的范围以及激活岩块大小等。根据实测数据,指出地下核爆炸诱发工程性地震的力学本质,利用理论公式计算了地下核爆炸产生不可逆位移的临界能量因子范围,为相关研究提供理论基础和场地效应试验数据。
The huge energy released instantaneously in underground nuclear tests leads to a chain reaction of crustal energy,and results in geophysical phenomena such as induced earthquakes.This paper sorts out and sums up the underground nuclear test data of the Soviet Union and the United States conducted in the 20th century,including the range of engineering earthquakes induced by underground nuclear tests and the size of activating rock blocks.By judging the measured data,the mechanical nature of the engineering earthquake induced by underground nuclear explosion is pointed out and the range of the critical energy factor of irreversible displacement induced by underground nuclear explosion is calculated using the theoretical formula,thereby providing a theoretical basis and site effect test data for relevant researches.
