摘要
在第四系中更新统洪积粘土层中进行了现场试验研究 ,在 8.5～ 12 .5 m的埋深范围内爆扩成型 9个无衬砌腔体。装药量在 15～5 1kg,成腔容积在 5～ 2 0 m3。针对计算土中爆炸成腔半径的半经验公式 。
On Site experimients are carried out in mid Pleistocene series diluvial clay blanket of Quaternary system. Nine of no lining cavity are explosive enlarged in the depth of 8.5～12.5m. The explosive charges are at the weight of 15～51kg. The explosive cavities are at the capacity of 5～20m 3. Against the semi rational calculation formulas on radius of explosive cavity in soil, the proportion factors suitable for different explosives and their reduction formula are put forward.
