摘要(Abstract):

以黄河内蒙古段厚冰冻层为试验对象,开河前期进行了厚冰层的爆破破冰试验。试验采用专门研发的破冰产品,从冰面接触聚能爆炸和冰下水中爆炸两种破冰方式,分析了冰层的破碎机理和爆破振动、水中冲击波压力的变化特征及对周围环境安全的影响。研究成果对破冰产品研制、人工干预开河、江河冰凌灾害治理及环境安全控制等具有理论研究和应用价值。
Experiment study on the blasting upon thick ice in the inner Mongolia section of the Yellow River was carried out.Special breakage ice product was applied in the experiment.The breakage mechanism of ice blasting,the variation characteristics of blasting vibration and shock wave pressure in water,and the influence on security of surrounding environment were analyzed by shaped contact explosion on the ice and explosion in the water below the ice.The results obtained by study are of theoretical value and guidance significance to research and manufacture of breakage ice production,the practice of blasting breakage ice,prevention of ice-jam flood disaster and safe control of environment.
