摘要
结合典型实例,阐述了冰凌危害,指出黄河凌汛是最大的无讯潜伏灾难,必须加强研究遏制冰凌危害的有效科学方法。本文推导了冰凌下延长药包爆破破冰的药量计算公式,并在黄河冰凌爆破中进行了试验研究,取得了理想的效果。证明了所推导的药量计算公式是科学合理的,所应用的施工工艺也是可行的。试验的结果对于今后黄河冰凌爆破的进一步研究,有重要的现实意义。
With typical instance,the ice damage was introduced.It was pointed that the Yellow River was the largest potential disaster without information and the research must be strengthed against the eff-ective and scientific method to contain ice.A calculation formula of charge mass on ice breaking by extended blasting cartridge under ice was deduced,and experimental study was made in the process of ice breaking in Yellow River,which achieved good results.The results showed that the deduced formula was scientific and the construction techniques were also feasible,which had very important practical significance for the further study of Yellow River ice blasting in future.
