| Abstract: | This paper provides a formula for calculating ground surface shock motion induced by underground contained explosions and presents two isolation methods which can be taken in strong shock surroundings. Results show that when the ground surface velocities are 3. 45m/sand 4. 8m/s, the isolating coefficients of the sand mat and the isolating bed are 11. 69% and 12.05% respectively. |
