摘要
本文给出了地下封闭爆炸近区地表冲击运动参数计算公式，介绍了在强冲击环境中采用的两种隔离措施。事件Ａ和事件Ｂ的实用结果表明：当地表冲击速度为３．４５ｍ／ｓ和４．８ｍ／ｓ时，砂垫层组合隔离系统和隔离床系统的冲击隔离系数分别为１１．６９％和１２．０５％。
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.
