Abstract To break through the limitation of long-term dependence on limited test data for estimating the ground shock power of underground explosion，based on the systematic review of the research results at home and abroad，this paper systematically analyzed the coupling mechanism of ground shock and crater effect of large equivalent underground explosions，theoretically revealed the law of volume of underground explosion damage zone and coupling ground shock energy，the theoretical calculation method and conversion relationship of equivalent coefficient，ground shock energy coupling coefficient and ground shock stress coupling coefficient are established. Finally，the calculation methods of shock stress and particle velocity under different buried depths are systematically given，and the accuracy of the theoretical model and calculation formula under the conditions of chemical explosion and nuclear explosion is verified by field test and model test.

Key words： mechanics of explosion underground explosion critical depth ground shock coupling coefficient model test
