摘要
采用 3 kg、5 kg和 10 kg装药在自由场中爆炸 ,观察分析距炸点不同距离的家兔在爆炸冲击波下的伤亡情况。试验同时使用冲击波超压测量仪记录不同位置的冲击波超压。试验结果表明 ,在超压小于 0 .0 8× 10 5Pa时家兔基本安全 ,3 kg、5 kg、10 kg炸药爆炸时的安全距离分别为 2 0 m、2 5 m、3 0 m。
The present article is inclined to introduce the authors' experimental research on the safe distance of the impact of the explosive blast on human beings and other animals. To examine and analyze the casualty caused by the blast intensity on human and other beings, the authors put rabbits on different distances to the blasting point with different strengths of the mass, like 3 kg, 5 kg and 10 kg. While doing the experiment, the authors were recording the overpressure at various distances. The experimental results indicate that the rabbits under the testing were safe while the overpressure is less than 0.08×10~5 Pa. However, when the overpressure is 0.08×10~50.2×10~5 Pa, the rabbits would be suffering cardiac bleeding and pulmonary edema. Furthermore, when the overpressure exceeded 0.2×10~5 Pa, the rabbits would be injured so severely as to die. Thus, it can be concluded that the safe distances should be 20 m, 25 m and 30 m when the mass of 3 kg, 5 kg and 10 kg TNT are blasting.
