Abstract

Abstract

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.
